Anahita Saxena from Ryan International School Pune, Pune
Class : Class 3
Well, the correct answer is showing D. I mean is D is the correct answer? No, it is not. If u see here the answer will be C. How? This is the life cycle of a frog - First it other frogs lay eggs. Then it grows to a tadpole. Then to a froglet. And then lastly it grows into an adult frog. So, it has 4 stages. And then for cockroach, it has 3 stages which are - Eggs into a Nymph and then into an adult cockroach. So, that is why the correct answer will be C and not D.

Ans 2:

Sriyansh from Surabhi , Hosapete
Class : Class 9
The correct answer is 'd'. M/s^2 or metre per second square. That is because the formula for acceleration is change in velocity /time. The SI unit of velocity is m/s (as it is displacement /time) and the SI unit of time is second. So the SI unit of acceleration is m/s/s which can also be written as m/s^2

Ans 3:

rethish from Veltech, Avadi

Ans 4:

A Kumar from SNSVM, East Singhbhum
