The leopard frog and the pickerel frog are two closely related species. in areas where their ranges overlap, the frogs will remain separate species if they a) maintain different colored markings on their skin. b) eat different types of insects and crustaceans. c) occupy burrows in different parts of a creek. d) reproduce at different times of the year.

 Option D

The closely related species can share their habitat. In the areas where both the frogs (leopard and pickerel) overlap each other can be separated.

There are different types of mechanism available for the isolation such as mechanical, behavioral or the various types of physiological processes.

The frogs will remain separated from each other if they will reproduce at different times of the season.
