Key property: If \(\frac{a}{b} = 0\), then \(a\) must equal zero
Given: \(m + n\) is an integer
So, \(\frac{1}{m + n}\) is the reciprocal of \(m+n\)
In order for \(\frac{1}{m + n}\) to equal zero, the numerator must be zero.
Since the numerator of \(\frac{1}{m + n}\) is already 1, we know that \(\frac{1}{m + n}\) can never equal 0
Answer: C
