Which statement(s) is/are WRONG?

Options

A. (a) Acetylene is insoluble in conc. `H_2SO_4` due to not formation of vinyl carbocation
`(CH_2=overset(o+)CH) (HSO_4^(-))`.
B. (b) Ethylene is soluble in conc. `H_2SO_4` due to the formation of alkyne carbonation
`(H_3C-overset(o+)CH_2) (HSO_4^(-))`
C. (c) But-2-yne dissolves in conc. `H_2SO_4` due to the formation of vinyl carbocation `(Me-overset(o+)C=CH-Me)(HSO_4^(-))`, but it is stabilised by electron-donating methyl group and is more stable than the vinyl carbocation formed from acetylene.
D. (d) More the s character in the positively charged C, the more stable is the carbocation and more likely is its formation.
