To simplify the expression \((2u - 7y) - (7u + 2y)\), we can distribute the negative sign to the second set of parentheses:
\[ (2u - 7y) - 7u - 2y \]
Now, we combine like terms. First, we'll combine the \(u\) terms:
\[ 2u - 7u = -5u \]
Next, we'll combine the \(y\) terms:
\[ -7y - 2y = -9y \]
Putting it all together, we get:
\[ -5u - 9y \]
Thus, the answer is:
\[ \boxed{-5u - 9y} \]
So the correct response from your options is "negative 5 u minus 9 y".
