• C. A is true but R is a false statement
• D. Both A and R are false statements

Answer 1

The correct option is C A is true but R is a false statement

Spring wood or early wood is lighter in color with large wide vessels while autumn wood or late wood is darker in color with narrow vessels. Both these constitute the annual rings or the growth rings of the plant.

Both spring and autumn are of equal duration of three months. The cambium is more active during the spring season compared to winter when the cambium is less active.
