Solution

The correct option is D Both Assertion and Reason are incorrect
Disruptive type of selection favours both small-sized and large-sized individuals. It eliminates most of members with mean expression, so produces two peaks in the distribution of the trait that may lead to development of two different populations. This kind of selection is rate in nature but is very important in bringing about evolutionary change.
So, the correct answer is 'Both Assertion and Reason are incorrect'.
