Tuber	Rhizome	Bulb	Leaf buds

B.

A	B	C	D
Offset	Sucker	Stolon	Leaf buds

C.

Offset	Stolon	Sucker	Leaf buds

D.

A	B	C	D
Tuber	Rhizome	Bulbil	Leaf buds

Answer 1

Hint:
The figures provided in the question represent different modifications of stems and roots. These modifications help in overcoming unfavourable conditions and adapting to a certain environment. These differ from each other either structurally, physiologically, or morphologically

Complete answer:
Figure A represents a node which means it's a stem; a leaf scar which also points out it is a stem; a bud which shows that this stem functions for storage of food. It is round and swollen. Thus, based on all these characteristics, we can say that it is a tuber.
Figure B represents a horizontal structure with many nodes. This tells that it is a stem. Many adventitious roots are growing from it. It appears to be fleshy and the presence of buds implies that it stores food for the inactive stages of the plant. This tells us that this is a rhizome.
Figure C showcases a number of structures called bulbils which arise from the axillary bud. These are shown to be situated on the axis between the leaves and the stem.
Figure D shows many offshoots growing out from the leaves, labeled as buds. These are named adventitious because of the fact that these are not growing from the apices of the stem or its nodes but from leaves. These can be used to propagate new plants.
Thus, the correct answer is:

A	B	C	D
Tuber	Rhizome	Bulbil	Leaf buds

Option ‘D’ is correct

Note:
Tuber and Rhizome are different types of stem modifications. Bulbils and leaf buds arise from axillary buds.
