  3. 1 and 3 only
  4. 1, 2 and 3

Answer

1 and 3 only

1. Vegetative propagation produces clonal population. — Correct. New plants arise from somatic parts of a single parent, so they are genetically identical clones.

2. Vegetative propagation helps in eliminating the virus. — Incorrect. Ordinary vegetative propagation usually transmits the same viral infection from parent to offspring; virus elimination is done through special methods like meristem culture, not vegetative propagation itself.

3. Vegetative propagation can be practiced most of the year. — Correct. Since it does not depend on flowering, pollination, or seed set, many vegetative methods can be carried out through much of the year under suitable conditions.

Hence, statements 1 and 3 only are correct.
