To which group does the lac insect belongs?

Answer: Option C

The lac insect belongs to group Homoptera.
Homoptera is a suborder of order Hemiptera that is considered by some taxonomists to be paraphyletic.
Lac is the resinous secretion of several species of lac insects, of which the most commonly cultivated is Kerria lacca. These are in the superfamily Coccoidea, the scale insects. This species is perhaps the most commercially important lac insect, being a main source of lac, a resin that can be refined into shellac and other products.
