The correct answer is: C.Sea lion populations increase due to less predation.

A. Sea lion populations migrate away

While migration could happen in response to environmental factors, it is not the most likely response to reduced orca predation. The primary effect would be on their population size, not migration.

B. Sea lion populations remain unaffected

This is unlikely. Orcas are known predators of sea lions, and a reduction in orca numbers would likely have an impact on the sea lion population by reducing predation pressure.
