If x and y are positive odd integers, which of the following statements could be false?

I. x^y is an odd integer

II. x^y +y^x is an odd integer

III. y/x is not an integer

I think the answer PR gives is wrong...

II. and III.

I. x^y is an odd integer. true.
II. x^y +y^x is an odd integer. not true. this rresults in an even integer.
III. y/x is not an integer. not true. this could result in an integer.
