When 2-butyne is brominated, A is formed . When 2-butyne is reacted with `HgSO_4` and `H_2SO_4` , then B is formed which then gives C . Hence
A.
B.
C. B is `Me-undersetunderset(OH)|C=CH-Me` and C is `Me-oversetoverset(O)(||)C-CH_2-CH_3`
D. B is `Me-undersetunderset(OH)|oversetoverset(OH)|C=CH-Me` and C is `Me-oversetoverset(O)(||)C-CH_2-CH_3`
