Answer 1

The correct option is B (B) - (i) white-winged moth, (ii) dark-winged moth (C) - (i) use and disuse

After industrialisation the white moth did not survive due to predators but the dark winged moth survived easily because they could hide in the dark background of the bark of trees.

According to Lamarck the use and disuse of organs later lead to the evolution.

So, the correct answer is '(B)-(I)white-winged moth, (ii)dark-winged moth, (C)-(I)use and disuse'
