Copy each figure. Use a composition of reflections to find the rotation image with respect to lines m and t.

I need an explanation for this.

What do you get if you reflect the original figure in the line m and then reflect that in the line l? Or you could do it in the opposite order.
Can you then see that your final image could be obtained by a single rotation?

So, the reflection would be B

If by B you mean the second diagram, then yes.
