The lowest stability of ethyl anion compared to methyl anion and the higher stability of ethyl radical compared to methyl radical, respecticely, are due to
A. `+l`effect of the methyl group in ethyl anion and `sigmato` p-orbital conjugation in ethyl radical.
B. `-l` effect of the methyi group in ethyl anion and `sigmatosigma*` conjugation in ethyl radical.
C. `+l` effect of the methyl group in both cases
D. `+l` effect of the methyl group in ethyl anion and `sigmatosigma*` conjugation in ethyl radical.

Correct Answer - A
`CH_(3)-overset(-)CH_(2)` is less stable than `overset(-)CH_(3)" as the "CH_(3-)` group exert +I effect `CH_(3)-CH_(2)` radical is more stable than `CH_(3)`, this is due to `sigma-p` conjugation, also knows as hyperconjugation.
