BSilk                  Sheep               Butterfly
CWoollen           Plant                 Moth
DNylon              Sheep                Silver fish


Please sir I found this a very dicey question. Do silver fish really damage silk and woolen clothes?

Ans 1:

Class : Class 5
Option no. D is correct. This is because as nylon is a synthetic fibre , it doesn't absorb sweat and also sheep is the animal from whom wool is obtained, and yes silverfish do damage silk and woollen clothes.
