• D. Woolen cloth, plastic bag, cotton cloth, paper

Answer 1

The correct option is C Plastic bag, woolen cloth, cotton cloth, paper

$\bullet$ A material which gets decomposed through natural processes, such as action by bacteria, is called biodegradable.
$\bullet$ Paper takes approximately 10 to 30 days to degrade.
$\bullet$ Cotton cloth takes approximately 2 to 5 months to degrade.
$\bullet$ Woolen cloth takes approximately 1 year to degrade.
$\bullet$ Plastic bag takes several years to degrade.

Hence the correct order is: plastic bag, woolen cloth, cotton cloth and paper.
