Reason (R ) Rayon is a semisynthetic polymer and is taken as a better choice than cotton fabric
Reason (R ) Mechanical and aesthetic properties of cellulose can be improved by Acetylation

A

Assetion and Reason both are correct statement But reason does not explain Assertion

B

Assertion and Reason both are correct statements and Reason explains the Assertion.

C

Both assertion and reason are wrong sttement s

D

Assertion is correct statement and Reason is worng statement.
