temporal reproductive isolation

Explanation:

The correct answer would be temporal reproductive isolation.

Reproductive isolation generally refers to series of biological mechanisms or processes that prevent members of different species from mating/fertilization or prevent the product of their mating to be invalid.

Some reproductive isolation processes prevent members of different species from mating or prevent fertilization as a result of mating. These processes are known as pre-zygotic reproductive isolation mechanisms.

Some other processes ensure that the product of fertilization (when it occurs) is invalid. These are known as post-zygotic isolation mechanisms.

A good example of the pre-zygotic reproductive isolation process is when closely related by different species bloom at different times. This will prevent mating or cross-pollination to happen between the different species. This is known as temporal reproductive isolation.
