Solution
The correct option is D I and II can be used
Cutting is a method of artificial vegetative propagation in which a stem or a branch from a healthy plant is cut off and planted in the soil. This cutting then develops into an independent plant.
Tissue culture is a technique that involves separating some tissue from the parent plant and then growing it in an artificial medium.
In plants, regeneration is a mere mechanism of replacing or repairing damaged parts of the plant. Hence, it cannot be used to grow a new plant or rejuvenate the population of the plant in question.
