Correct option is B
Solution:
The logic follows here:
INSECT : LARVA → A larva is an insect at the stage of its life after it has developed from an egg and before it changes into its adult form.
Similarly,
BUTTERFLY : CATERPILLAR → A caterpillar is a butterfly at the stage of its life after it has developed from an egg and before it changes into its adult form.
Hence,
"CATERPILLAR" is the correct answer.
