Maybe this can help you...

Relationship of high birth weight and adult obesity*—*LGA infants appear to have a propensity for adult obesity. However, most reports of later growth of LGA infants include only IDMs, whose altered metabolic state may potentiate the development of obesity and abnormal glucose metabolism. (See "Infant of a diabetic mother".)

Other studies report outcomes of all LGA infants and include both IDMs and nonIDMs [35,36]. As an example, a longitudinal study of 33,413 infants born in Israel compared birth weight to body mass index at 17 years of age [36]. Newborns weighing more than 4500 g were more likely to be overweight or severely overweight (body mass index >24.6 or 27.8 kg/m2, respectively) (odds ratio 2.16 and 2.3 for males and 2.95 and 4.39 for females) compared to AGA infants.

Environmental factors*—*Almost all obesity in children is strongly influenced by environmental factors, caused by either a sedentary lifestyle or a caloric intake that is greater than needs. The contributions of specific environmental influences are the subject of considerable discussion and research. Increasing trends in glycemic index of foods, sugar-containing beverages, portion sizes for prepared foods, fast food service, diminishing family presence at meals, decreasing structured physical activity, increasing use of computer-oriented play activity, and elements of the built environment (eg availability of sidewalks and playgrounds) have all been considered as causal influences on the rise in obesity [36]. In particular, a number of well-designed studies have shown associations between intake of sugar-containing beverages or low physical activity and obesity or metabolic abnormalities [37-43]. Causal associations seem likely but are difficult to establish with certainty.

Genetic factors*—*Genetic factors play a permissive role and interact with environmental factors to produce obesity. Studies suggest that heritable factors are responsible for 30 to 50 percent of the variation in adiposity [80], but most of the genetic polymorphisms responsible have not yet been isolated. Thus, genetic contributions to common obesity likely exist, but most of the molecular mechanisms for these factors have yet to be determined.

i would go with A

but many of my friends tell me that genetic factor is most important here

because you find many people who may eat a lot but they still thin others eat even a little but they become obese because of that i am confuse about this

Are you looking for most important or most common. I assume that "most common" does not mean that everyone who has (or does) xyz gets the disease, it just means that a lot of people have that risk factor.

To me, if "almost all obesity in children" is STRONGLY influenced by lack of exercise and/or overeating, this suggests that food is a big contributing factor, though I'm not sure that high caloric intake necessarily refers to fast food.

That said, I've been thinking about how, based on my own (unscientific) observation, I would estimate that 95% of "young adolescents" eat a lot of fast food. On the other hand, I definitely wouldn't estimate that 95% of US children have genetic and/or high birth weight risk factors. Therefore, if asked for the "most common" risk factor among American adolescents, I would say fast food hands down.

I think instead of just beating around the bush, if you find some specific question on this topic it will lead to a more concrete discussion
