Solution

The correct option is D Both assertion and reason are false
Micropropagation is the rapid vegetative propagation of plants under in vitro conditions of high light intensity, controlled temperature and a defined nutrient medium.
Each of these plants will be genetically identical to the original plant from which they were grown, i.e., they are somaclones. Hence micropropagation cannot be used to introduce variations in the offspring.
It is possible to generate virus-free plants through micropropagation by obtaining meristem cells from the plants as meristems are free from virus.
