Hello,
The answer is option A "predict the genotypic and phenotypic probabilities of possible offspring".
Reason:
A Punnett square is used to determine (predict) the genotype, and phenotype of a organism. Phenotype is the physical features of a organism fur, ears, nose, etc.... Genotype is most likely the height, eye color, etc....
If you need anymore help feel free to ask me!
Hope this helps!
