Options
- Ai-a, ii-d, iii-b, iv-c
- Bi-d, ii-c, iii-b, iv-a
- Ci-a, ii-b, iii-c, iv-d
- Di-c, ii-d, iii-a, iv-b
Correct answer
D. i-c, ii-d, iii-a, iv-b
Step-by-step solution
Stem tendril is a structural modification of stem for mechanical support, e.g., strawberry, cucumber. Fleshy stem known as the phylloclade is a modification of plants like Opuntia in dessert regions in order to conserve water and perform photosynthesis. Woody thorns are seen in plants like citrus for protection for herbivores. Horizontal stems are seen in plants like strawberry which help them propagate vegetatively.
