Best answer

Answer: 2. Both A and R are true and R is the correct explanation of A.

Key idea: In winter the cambium is less active and forms fewer xylary elements with narrow vessels. This is the late wood (autumn wood), which is darker and denser.

A is true, and R gives the reason for it, so R explains A. Option 2.
