• B. Less
• C. Normal
• D. None of the above

Answer 1

The correct option is A More

In the plants growing temperate regions, the activity of vascular cambium is influenced by existence of maximum seasonal variations. In the spring or early summer, due to the existence of favourable conditions, large amount of secondary xylem is formed. it is called Spring wood or early wood. In the autumn season, due to the presence of unfavourable conditions, less amount of wood is formed. it is called autumn wood or late wood.

So, the correct option is 'more'.
