Option (3) Meristem — Correct. Although a plant is infected with a virus, its meristem (apical and axillary) is free of virus. So the meristem is removed and grown in vitro to obtain virus-free plants.
NCERT Extract:
Biotechnological Applications in Agriculture – “… Another important application of the method is the recovery of healthy plants from diseased plants. Even if the plant is infected with a virus, the meristem (apical and axillary) is free of virus. Hence, one can remove the meristem and grow it in vitro to obtain virus-free plants. Scientists have succeeded in culturing meristems of banana, sugarcane, potato, etc.”
