Solution

The correct option is C L could be nucleus whereas O could be peroxisome
L is a nucleus that is double layered and directs cell growth and its activities. M is a chromoplast which gives colour to fruits. N is lysosome which digest foreign materials and O is peroxisome that has hydrogen peroxide that carries out oxidative reactions.
So the correct answer is "L could be nucleus whereas O could be peroxisome".
