Step 1:

Write out the expression


(7n^7-4n^6-14)\text{ - (}2n^7+15n^6+11\text{)}

Step 2:

Multiply out and note that all signs in the second bracket will change.


\begin{gathered} 7n^7-4n^6-14-2n^7-15n^6\text{ - 11} \\ \text{Collect similar terms} \\ 7n^7-2n^7-4n^6-15n^6\text{ - 14 - 11} \\ =5n^7-19n^6\text{ - 25} \end{gathered}

Option A is the correct answer
