Answer #1

Factors present in the environment that cause mutations are known as mutagens. These mutagens include ionisation ( ionizing radiations like X-rays, gamma rays), chemicals (like alkylators) and infectious agents. Mutations caused by these mutagens are known as induced mutations.

Hence, the correct option is (B) Induced mutations.

Option (A) is incorrect because spontaneous mutations are caused by the occurrence of errors in the natural biological processes like sickle cell anemia.

Option (C) and (D) are incorrect because missense mutation and cancer can be caused by both biological and environmental factors.
