Solution

The correct option is C Lignin
Lignin is the complex polymeric molecule composed of phenylpropanoid units associated with cellulose (as lignocellulose) in cell walls of sclerenchyma, xylem vessels and tracheids, making them strong and rigid. After cellulose, lignin is the most abundant plant polymer, forming 20-30% of the wood of the trees.
So, the correct answer is option C.
