Answer 1

Right choice is (b) Any part of a plant taken out and grown in a test tube

To elaborate: It was learnt by scientists, during the 1950s, that whole plants could be regenerated from explants, i.e., any part of the plant taken out and grown in a test tube, under sterile conditions in a special nutrient medium.
