Answer: Choice D
===================================================
Step-by-step explanation
The translation vector MN is <3, -4>
It is the same as writing
which means "shift 3 units right, and 4 units down".
We apply this translation rule to each point J, K, and L.
Let's do so to point J.

J(-1,2) moves to J ' (2, -2)
This narrows the answer to choices B, C, or D.
Follow similar steps for point K.

K(-2,-1) moves to K ' (1, -5)
Therefore, the answer is choice D
For the sake of completeness, let's move point L.

L(2,1) moves to L ' (5, -3)
This matches with answer choice D as well.
