If x and y are integers and x + y = 8, which of the following must be true?	Choose the correct answer
A) x and y are consecutive integers.	B) Both x and y are even.	C) If x > 0, then y < 0.	D) If x < 0, then y > 0.	E) Both x and y are less than 5.
In option C if x &gt; 0,then y&lt;0 means x is +ve and y is -ve   In option B if x &lt; 0, then y&gt;0 means y is +ve and x is -ve, both are same and satisfying x+y = 5.   How option If x &lt; 0, then y &gt; 0. is right could you explain
