Solution
a and b both are correct.
Cells of onion peel are surrounded by a cell wall whereas the RBCs (red blood cells) do not have cell walls. When the cells of onion peel and RBCs are separately kept in a hypotonic solution, RBCs will first swell up and then burst due to endosmosis. However, the cell wall in the cells of the onion peel exerts a counter wall pressure when the cells become fully turgid. This stops further entry of water into the cells and thus the cells do not burst.
