Compare the stabilities of the following corbocation
`(a) overset(+)CH_(2) overset(..)(NH_(2)) " "(b) overset(+) CH_(2) - underset(..)overset(..)(OH) " "(c) overset(+) CH_(2) - underset(..) overset(..)F:`

Explanation

To compare the stabilities of the given carbocations, we will analyze each structure and the effects of substituents on the stability of the carbocation.

### Step 1: Draw the Structures
1. **Carbocation A**: \( \overset{+}{\text{C}}H_2 - \text{NH}_2 \)
2. **Carbocation B**: \( \overset{+}{\text{C}}H_2 - \text{OH} \)
3. **Carbocation C**: \( \overset{+}{\text{C}}H_2 - \text{F} \)

### Step 2: Analyze the Effects of Substituents
