Which of the following carbocation is most stable ?
(a) `(CH_(3))_(3)C.overset(+)CH_(2)` (b) `(CH_(3))_(3)overset(+)C` (c) `CH_(3)CH_(2)overset(+)CH_(2)` (d) `CH_(3)overset(+)CHCH_(2)CH_(3)`

Explanation

To determine which carbocation is the most stable among the given options, we can analyze the stability based on the number of alpha hydrogens and the degree of substitution of the carbocation.

### Step-by-Step Solution:

1. **Identify the Carbocations**:
- (a) `(CH₃)₃C⁺CH₂`
- (b) `(CH₃)₃C⁺`
- (c) `CH₃CH₂⁺CH₂`
