If x is an odd negative integer and y is an even integer, which of the following statements must be true?
I. (3x - 4y) is odd
II. xy^2 is an even negative integer
III. (y^2 - x) is an odd negative integer  Options.
A) (3X-4Y) IS ODD TRUE  B) II only  C) I and II  D) I and III  E) II and III
If x is an odd negative integer and y is an even integer, which of the following statements must be true?   I. (3x - 4y) is odd   3x - is always negative and odd   2y - can be 0, when y=0, or always even integer (positivie or negative)   odd integer +/- even integer = always odd   I statement is always true   II. xy^2 is an even negative integer   y can be 0 =&gt; xy^2 = 0 (non-negative even) =&gt; II statement is not true   III. (y^2 - x) is an odd negative integer   y can be 0 =&gt; -x will be positive =&gt; III statement is not true   basing on above, only I statement will always be true   answer is (3X-4Y) IS ODD TRUE
