By looking at a gene set up or a punnet square,a gene that's dominant would be represented by a capital letter and recessive traits are represented by lowercase letters for example brown eyes are considered a dominant trait which can be represented as BB for homozygous, and Bb for heterozygous. Since blue eyes are recessive they would be bb.

Shark pups with the most advantageous traits are more likely to survive and reproduce. For example, pups that can hunt and feed

Ronch [10]

The answer is B. This is called genetic shift. The pups with advantageous traits are able to survive until the age of reproduction hence able to pass their genes to the next generation. Few and fewer pups with disadvantageous traits will get to reproduce hence the allelic frequencies of the shark population will shift in favour of increased hunting efficiency.
