Answer:
Option C
Explanation:
Long term hunting has led to following  
a)	Reduction in population size and hence the gene pool
b)	Causation of Bottleneck effect
Due to above factors, the remaining population of Northern elephant seals does not represent the original genetic problem.  
Due to this restriction in mating and genetic variation shall prevail pertaining to reduced gene pool.  
Due to continuous hunting, the gene pool will further shrink, leading to genetic similarity among the organism
Option C is correct
