Consider the given two statements:
Assertion (A): Tertiary carbocations are generally formed more easily than primary carbocations.
Reason (R): Hyperconjugation as well as inductive effect due to additional alkyl groups  stabilize tertiary carbocations.
 
1. Both (A) and (R) are True and (R) correctly explains (A)
2. Both (A) and (R) are True but (R) does not correctly explain (A)
3. (A) is True but (R) is False
4. Both (A) and (R) are False
