the answer is 'b' .The plant cell does not burst in hypotonic solution because the plant cell wall exerts an equal pressure as exerted by the liquid in the cell.So this prevents it from bursting but after sometimes, the plant cell will burst.

Why is the answer D? This is because it says that woodlice are found typically under damp rotting leaves. For the test, Sanika kept rotting leaves on dry and damp soil. If you read the question carefully, you will find that Sanika had stated that woodlice needed a damp environment as a possible explanation as to why woodlice were found under damp rotting leaves. She even placed the woodlice pointing to the rotting leaves with damp soil under it. Based on this, she was most probably testing the 4th explanation she stated and so that, my friends, is why option D is the correct answer.
