Options

  1. AA-I, B-II, C-III
  2. BA-III, B-II, C-I
  3. CA-II, B-I, C-III
  4. DA-III, B-I, C-II

Correct answer

D. A-III, B-I, C-II

Step-by-step solution

According to NCERT, Bt toxins are insect group-specific. The proteins encoded by cry genes are effective against various types of insects. Lepidopterans include tobacco budworm and armyworm. Coleopterans include beetles. Dipterans include flies and mosquitoes. Therefore, the correct matching is A-III, B-I, C-II. Answer: A-III, B-I, C-II
