Question

The greater stability of tert-butyl carbocation over methyl carbocation can be explained on the basis of :
(1) $+I$-effect of the methyl group
(2) hyperconjugation effect of the methyl group
(3) electromeric effect of the methyl group
(4) $-I$-effect of the methyl group

• A. 1, 2 and 3 are correct
• B. 1 and 2 are correct
• C. 2 and 4 are correct
• D. 1 and 3 are correct
