Correct Answer
B

Because they lack secondary growth

Your Answer
C

Due to too much primary growth

Your Answer
D

They do not produce lignin to harden the stem


Solution

The correct option is A

Because they lack secondary growth


Stems of angiosperms can undergo two types of growth - primary and secondary. While primary growth increases the length, the secondary growth increases the girth of the stem and this leads directly to the hardening of the stem.
