Correct

Answer A.
At 912 months, infants gradually develop the concept of object permanence, or the understanding that objects exist even when they are not seen. Around the time this milestone is achieved, infants develop frontal activity on the electroencephalogram. Infants first apply this concept of object permanence to the image of their mother because of her emotional importance; this realization is a critical part of attachment behavior.
