(D) The reaction of acetylene $(CH \equiv CH)$ with $HBr$ proceeds via electrophilic addition.First,one molecule of $HBr$ adds to acetylene to form vinyl bromide $(CH_2 = CHBr)$.Then,a second molecule of $HBr$ adds to the vinyl bromide following Markovnikov's rule to form ethylidene dibromide $(CH_3CHBr_2)$.The reaction is: $CH \equiv CH$ $\xrightarrow{HBr} CH_2 = CHBr$ $\xrightarrow{HBr} CH_3CHBr_2$.
