Answer:
c. the neutral theory posits that the vast majority of mutations do not influence the fitness of individuals
Explanation:
The neutral theory proposed by Motoo Kimura states that the vast majority of changes at the molecular level (DNA) in a population happens due to genetic drift, not by natural selection, this implies that the mutations are neutral and do not give an advantage to the organisms.
This means that mutant alleles are preserved due to the randomness of life and not because this alleles give selective advantage over other individuals of the population.
Salinity refers to an increase in the dissolved salt content of a body of water. Salinity has great impacts on the type of organisms that live inside the water. In the question given above, the salinity occurs as a result of non natural influence; since most of the organisms living inside the water before probably have specific optimal salinity range, if the salinity exceed the range they can cope with, they will probably migrate away from the water, those that refuse to migrate will probably die out and new species which can cope with the salinity level will emerge.
