Question

Assertion : Bacterial cell wall is characterised by having mucopolysaccharides.
Reason : Acetyl muramic acid is an example of mucopolysaccharide.
A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion

C. If the assertion is true but the reason is false
