Given below are two statements: 
Assertion (A): In \(\alpha \text-\text{decay}\) atomic number of the daughter nucleus is reduced by \(2\) units from the parent nucleus.
Reason (R): An \(\alpha \text-\text{particle}\) carries four units of mass.
 
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.
