Answer:

Correct Answer: C

Solution:

[c] Spring wood is the part of an annual ring of wood, characterised by large, thin-walled cells, formed during Ae first part of the growing season.

It is lighter in colour with low density.

It produces a larger number of xylem elements having vessels with wider cavities.

Autumn wood or late wood is the wood element formed during winter when cambial activity is more.

It is darker in colour with high density.

Wood elements are lesser in amount and have narrow lumen.
