Detailed explanation-1: -Examples of temporal isolation include differences in mating behaviors or fertility due to the time of day, time of year, or varied mating cycles. Two species which are temporally isolated long enough may eventually accrue enough genetic differences that they will no longer be able to interbreed.

Detailed explanation-2: -So, the correct option is ‘Mule’.

Detailed explanation-3: -a) Temporal isolation. Individuals of different species do not mate because they are active at different times of day or in different seasons. b) Ecological isolation. Individuals mate in their preferred habitat, and therefore do not meet individuals of other species with different ecological preferences.

Detailed explanation-4: -Sympatric speciation is more common in plants. For instance, parent plants produce offspring that are polyploid. Hence, even if the offspring thrive in the same location as their parents they may be “reproductively” isolated.
