Assertion (A): Hydrolases are the enzymes which catalyse the hydrolysis of ester, ether, peptide and glycosidic bonds.
Reason (R): Lyases functions as ligases.
 
1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is not the correct explanation of (A).
3. (A) is true but (R) is false.
4. Both (A) and (R) are false.
