Options
- AA-5, B-1, C-4, D-2
- BA-3, B-1, C-4, D-2
- CA-3, B-1, C-2, D-4
- DA-1, B-3, C-4, D-2
Correct answer
B. A-3, B-1, C-4, D-2
Step-by-step solution
In Bougainvillea , the axillary buds of the stem are modified into woody, straight, and pointed thorns (A-3). In pea, the leaves are modified into tendrils for climbing (B-1). Sweet potato has adventitious roots that get swollen and store food (C-4). In Rhizophora , many roots come out of the ground and grow vertically upwards. Such roots, called pneumatophores, help to get oxygen for respiration. They are modifications of the tap root system (D-2). Therefore, the correct matching is A-3, B-1, C-4, D-2. Answer: A-3
