If x and y are integers and x + y = 5, which of the following must be true?	Choose the correct choice from the following options
A) x and y are consecutive integers.
B) If x < 0, then y > 0.
C) If x > 0, then y < 0.
D) Both x and y are even.
E) Both x and y are less than 5.
Notice that the question asks which of the following MUST be true, not COULD be true.   Given: x + y = 5   A. x and y are consecutive integers: not necessarily true, for example x=1 and y=4;   B. If x &lt; 0, then y &gt; 0: if x is negative then y must be positive in order x+y to be positive, so this statement must be true;   C. If x &gt; 0, then y &lt; 0: not necessarily true, for example x=1 and y=4;   D. Both x and y are even: never true, as the sum of two even numbers is even and can not equal to odd number 5;   E. If x &lt; 0, then y &gt; 0.oth x and y are less than 5: not necessarily true, for example x=6 and y=-1;   Answer: If x &lt; 0, then y &gt; 0..
