Answer 2

Reason for resistance against pesticides:

• Option “D” is correct i.e. acquired heritable change.

• The most likely reason for the development of resistance against pesticides in insects damaging a crop is acquired heritable change.

• An acquired characteristic is a non-heritable change in a function of a living biotic material produced after birth by disease, injury, accident, thoughtful modification, repeated use, disuse or misuse, or other environmental factors. Acquired traits are not transferred on to offspring through reproduction alone.
