  3. CPrevalence of pesticide resistant insects
  4. DDevelopment of organs from ‘stem cells’ for organ transplantation

Correct answer

C. Prevalence of pesticide resistant insects

Step-by-step solution

According to Darwin's concept of natural selection, the organisms which are provided with favourable variations would survive because, they are the fittest to face their surrounding while the organisms, which are unfit for surrounding variations are destroyed. Prevalence of pesticide resistant insects is due to adaptability of these insects for the changes in environment (due to use of pesticides).
