D. - 4m, 7m

Step-by-step explanation:

Like terms are terms that can be added, subtracted, divided, and multiplied together. Since - 4m and 7m both have the variable m, they are like terms. 3mn is not a like term because it has two variables which makes it different form - 4m and 2n. It is its own term.
