The question is one of a dihybrid cross.
The picture that I attach below is a punnett cross of the parents (Yy Tt and Yy Tt).
So first you have to separate the two parents into gametes by pairing the alleles ( Yt , YT, yT, yt). Then I crossed then with the punnett square and from that we see that there are
two possible off spring that will would possess the genotype Yy TT (shaded gray in the diagram).
Thus the probability that a Yy TT offspring would be 2 out of 16

Answer:
Option A, Glucose metabolism in the fetal brain increased
Explanation:
Usage of cocaine during pregnancy is prohibited. However, in case if cocaine is taken it disrupts the metabolism as it increases brain glucose metabolism to the level of an adult human being. Since glucose metabolism in brain is a sensitive process, any disruption in it can lead to unaccounted effects such as dysfunctional circulation, and pharmacological effect. Cocaine increases the dopamine by blocking the dopamine transporters thereby increasing the Vmax. Since the brain of a child has all kind of neurochemical components, cocaine intakes by a pregnant woman produces reinforcing effects in brain of fetus and also make it pharmacologically active
Hence, option A is correct
