• B. Sucker
• C. Stolon
• D. Offset

Answer 1

The correct option is C Stolon

A- Underground stems of some plants spread to new niches and when older parts die new plants are formed. e.g., grass and strawberry.

B- In these plants, a slender lateral branch arises from the base of the main axis and after growing aerially for some time arch downwards to touch the ground. e.g., mint and jasmine.

C- A lateral branch with short inter-nodes and each node bearing a rosette of leaves and a tuft of roots are found in aquatic plants. e.g., Pistia and Eichhornia.

D- In these, the lateral branches originate from the basal and underground portion of the main stem, grow horizontally beneath the soil and then come out obliquely upward giving rise to leafy shoots. e.g., banana, pineapple, and Chrysanthemum.

So, the correct option is 'Stolon'.
