Solution

The correct option is B 3-chloro-1-butene
1,3-butadiene reacts with 1 mole of $H C l$ at low temperature ( $0^{0} C$ or below) to form 3-chloro-1-butene.
This reaction is kinetically controlled reaction and 1,2-addition of $H C l$ takes place.

$C H_{2} = C H - C H = C H_{2} + H C l 0^{0} C o r b e l o w - ------ \to C H_{2} C l C H_{2} C H = C H_{2}$

So answer is A.
