Default correct answer :)

The answer is B) Chorionic villus sampling

Chorionic villus sampling is a first-trimester diagnostic method for obtaining DNA for direct testing or chromosome analysis. It is routinely performed at 11 to 12 weeks gestation.

With luck your nausea will soon be on the wane and you'll begin to feel more energetic. You're probably also feeling relieved, because your risk of miscarriage has now dropped dramatically. For more info please visit motherhow.com/12-weeks-pregnant/
