Which of the following polymers is biodegradable ?

Options

A. `(-CH_(2)- underset(Cl)underset(|)(C) = CH - CH_(2))_(n)`
B. `(-CH_(2) - CH = CH-CH_(2)- CH_(2) - overset(CN)overset(|)(CH)-)_(n)`
C. `(-O -underset(CH_(3))underset(|)(CH) - CH_(2)- underset(O)underset(||)(C) - O - underset(CH_(3)CH_(3))underset(|)(CH) - CH_(2) - underset(O)underset(||)(C)-)_(n)`
D. `(-overset(H)overset(|)(N) -(CH_(2))_(6) - overset(H)overset(|)(N) - overset(O)overset(||)(C) -(CH_(2))_(4)-overset(O)overset(||)(C)-)_(n)`

Answer

C

Explanation

`(-O -underset(CH_(3))underset(|)(CH)- CH_(2)- underset(O)underset(||)(C) - O - underset(CH_(2)CH_(3))underset(|)(CH) - CH_(2) -underset(O)underset(||)(C)-)_(n)`
Poly `beta` - hydroxybutyrate - co - `beta` hydroxy valerat is an example of biodegradable polymer.
