View solution & NCERT explanation
Correct answer: A — If both assertion and reason are true and the reason is the correct explanation of the assertion.
Both statements are true from NCERT. NCERT states “Carcinogens are agents that induce transformation of normal cells into cancerous neoplastic cells” and “Ionising radiations like X-rays and gamma rays and non-ionizing radiations like UV cause DNA damage leading to neoplastic transformation.” The Reason explains HOW carcinogens cause cancer (Assertion) - by damaging DNA which leads to transformation.
