Vegetative propagation helps in eliminating the virus.3. Vegetative propagation can be practised most of the year.Select the correct answer using the code given below.

a1 only
b2 and 3 only
c1 and 3 only
d1, 2 and 3
✓ Correct answer: c) 1 and 3 only
ExplanationVegetative propagation is a fascinating form of asexual reproduction where new plants grow from specialized vegetative parts like stems, roots, or leaves rather than seeds.Statement 1 is correct: Vegetative propagation is a process in which new plants are grown from the vegetative parts of the parent plant.As this method does not involve sexual reproduction, the offspring are genetically identical to the parent, creating a clonal population.This technique ensures uniformity among the progeny, making it particularly useful for preserving desirable traits in cultivated plants.Statement 2 is incorrect: Standard methods of vegetative propagation generally do not eliminate viruses rather they often perpetuate viral infections because the new plants are exact genetic clones of the infected parent plant.Statement 3 is correct: Unlike seed-based propagation, which is often dependent on specific seasons, methods like cuttings, layering, or tissue culture can be carried out continuously as long as the required conditions and resources are provided. ​ Vegetative propagation can typically b
