Answer 1

The correct option is B autumn wood

Cambium activity is influenced by the climatic changes The cambium is more active during the spring that forms plenty of xylem vessels with wider cavities also called as early wood. In winter this activity slows down and gives rise to narrower xylem elements. This is the late wood or autumn wood.

So, the correct answer is, 'autumn wood'.
