Solution

The correct option is C Locomotion, Osmoregulation
Paramoecium is a unicellular organism and contains two nuclei namely the macronucleus and the micronucleus. The macronucleus controls all physiological activities like metabolism, locomotion, osmoregulation, digestion etc. While the micronucleus controls reproduction. Therefore, if the macronucleus of Paramoecium is damaged it will hamper all its life processes except reproduction.
So, the correct answer is 'Locomotion, Osmoregulation'.
