Answer

Explanation:

Step1: Remove parentheses

When we have ((m^{2}n^{2}-7)-(mn + 4)), we distribute the negative sign in front of the second - parentheses. So it becomes (m^{2}n^{2}-7 - mn-4).

Step2: Combine like - terms

There are no like - terms for (m^{2}n^{2}) and (-mn). For the constant terms (-7) and (-4), we combine them: (-7+( - 4)=-11). The resulting polynomial is (m^{2}n^{2}-mn - 11).

Answer:

C. (m^{2}n^{2}-mn - 11)
