Given data:

The given figure is shown.

The given coordinate of B is (3, 4) and the coordinate of B'(-5, 4).

It can be understand take first reflection about y-axis, then move 2 units left.


\begin{gathered} B^(\prime)=(-3-2,\text{ 4)} \\ =(-5,\text{ 4)} \end{gathered}

Thus, the option (B) is correct.
