d) it explains how domestic animals evolved.

The correct answer is option a.

Explanation:

Punctuated equilibrium refers to a term, which signifies the change in evolution of animals and plants in a comparative static manner. In contrary to the concept that life forms modify gradually with time in response to their surroundings, the theory of punctuated equilibrium states these changes takes place in shots of time intermittently.  

The term stands in contrary to Darwin's more dynamic evolution model. The punctuated equilibrium suggests that evolution only occurs in bursts of time, which are brisk.
