The correct option is D (i), (ii) and (iii)

All three statements are true.

All living organisms grow in size. For example. young ones of animals grow into adults.

All living organisms perform respiration. For example, all animals like cows, dogs, etc., take in oxygen, use it and then release the carbon dioxide produced in the process. Plants also perform respiration.

All living organisms respond to stimuli. Stimuli are the changes in the environment to which living organisms respond. For example, leaves of touch-me-not plant, close or fold when someone touches them. Another example can be of cockroaches moving to their hiding places when lights are turned on.
