What is the minimum energy required for the homolytic bond fission of the $C-H$ bond in the following molecule?

Which of the following carbocations is the least stable?

$A$ carbanion acts as a:

Most stable carbocation is

The following carbocation is stabilized by the interaction of the empty $p$ orbital with:

Given below are two statements:
Statement $I$: $(CH_3)_3C^{+}$ is more stable than $CH_3^{+}$ as nine hyperconjugation interactions are possible in $(CH_3)_3C^{+}$.
Statement $II$: $CH_3^{+}$ is less stable than $(CH_3)_3C^{+}$ as only three hyperconjugation interactions are possible in $CH_3^{+}$.
In the light of the above statements, choose the correct answer from the options given below.
