Your answer would be B.
Because, all the other answers could result in a decrease of the population of the specie (but it wouldn't be cyclic).

Answer:

The correct answer is option B.) "the vegetation it eats increases and then decreases repeatedly with changing seasons".

Explanation:

A cyclic population change is defined as a phenomenon at which organism populations rise and fall over a constant and predictable period of time. A reason that a species could undergo this type of populations changes is that the vegetation it eats increases and then decreases repeatedly with changing seasons. As a result the population of the primary consumer specie will increase and decrease at the same pace as the vegetation.
