The correct answer is: A.Seal populations increase due to reduced predation.

Explanation:

A.Seal populations increase due to reduced predation: This is the most likely effect. Polar bears are apex predators that primarily hunt seals for food. If polar bear populations decrease due to poaching, there would be less predation pressure on seals. As a result, seal populations are likely to increase due to reduced hunting by polar bears.

B.Seal populations decrease due to overgrazing: This option doesn't apply, as seals do not "overgraze." Overgrazing typically refers to herbivores eating too much vegetation, which doesn't ap...
