Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R:
Assertion A: Late wood has fewer xylary elements with narrow vessels.
Reason R: Cambium is less active in winters.
In the light of the above statements, choose the correct answer from the options given below:
- A
Both A and R are true and R is the correct explanation of A
- B
Both A and R are true but R is NOT the correct explanation of A
- C
A is true but R is false
- D
A is false but R is true
During winter the vascular cambium becomes less active and produces fewer, narrower xylem elements — this is autumn wood (late wood). The reduced cambial activity is the direct cause of the late-wood characteristics, so R correctly explains A.
