Yes, the correct answer is option (c) 1 and 3 only.

1. Vegetative propagation produces clonal population: In vegetative propagation, a new plant is produced from vegetative parts of the parent plant such as stem, root or leaf. The new plant is genetically identical to the parent plant, thus it produces clonal population.

2. Vegetative propagation helps in eliminating the virus: This statement is incorrect. Vegetative propagation can also lead to the transmission of viruses and diseases from the parent plant to the new plant. In some cases, viruses can also be carried over from generation to generation through vegetative propagation.

3. Vegetative propagation can be practiced most of the year: This statement is correct. Vegetative propagation can be practiced throughout the year as it does not depend on the season or availability of seeds. It is particularly useful for plants that do not produce seeds or have seeds that are difficult to germinate.
