Solution

The correct option is C Leather, paper, cloth
Biodegradable is the waste which can be degraded by the activity of microbes. The leather is obtained from the skin of the animals which is degradable. Paper is made from the wood and contains the cellulose which can be degraded by the microbes producing cellulase. Cloth contains cellulosic fibres which can be broken down by the microbes.
Thus, the correct answer is option C.
