    The stability of carbocations increases as we go from primary to secondary to tertiary carbons. There’s two answers as to why this is. The age-old answer that is still passed around in many introductory textbooks points to carbons (alkyl groups in particular) as being “electron-releasing” groups through inductive effects. That is, a carbon (electronegativity 2.5) connected to hydrogen (electronegativity 2.2) will be electron rich, and can donate some of those electrons to the neighboring carbocation.   In other words, the neighboring carbon pays the carbocation with electrons it steals from the hydrogens. The second, (and theoretically more satisfactory explanation) is hyperconjugation, which invokes stabilization through donation of the electrons in C-H sigma bonds to the empty p orbital of the carbocation.

    Option C This is based on the stability of carbocation formed . 3 degree carbocation more stable than a 2 or 1 degree carbocation due to the fact that in case of 3 degree carbocation there are three methyl group which increase the stability of carbocation due to its electron donating nature. In case of two degree carbocation there are two methyl groups while in case of primary carbocation there is only one methyl group
