C should be correct as when V increases U and T will also increase and when T increases then S will also increase so S will have the greatest population and U will be second populated the population of T will go as S will eat T but there is no one to eat U so S is the highest and then U (is the second highest)

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.
