Let's take each statement one by one.
(1) \(x - y - 1 > 0\)
\(x - y > 1\)
=> the difference between x and y is positive. The answer is yes. Sufficient.
(2) \(x - y + 1 > 0\)
\(x - y > -1\)
=> the difference between x and y can be positive, zero or negative. No unique answer. Insufficient.
The correct answer: A
Hope this helps!
