(a)

Interpretation:
The major product obtained from the reaction of given compound with excess of
Concept Introduction:
Addition of halides to alkynes: Halogens like chlorine and bromine adds to the alkyne compounds. The general form of the reaction is given below.
If excess halides are present, a second addition reaction also occurs.
