If a and b are positive integers, which of the following cannot be odd?  Select the correct option
A) (2+4a)/(4+4b)	B) (4a)/(b)	C) a/b	D) (4+a)/(2+4b)	E) (4+a)/(1+4b)
A. (2+4a)/(4+4b) - Under any condition this can't be odd. Answer   B. (4a)/(b) = 4.1/4 = 1 = Odd   C. a/b = 4/4 = Odd   D.(4+a)/(2+4b) = (4+2)/(2+4.1) = 1 = Odd   E.(4+a)/(1+4b) = (4+1)/(1+4.1) = 1 = Odd   (2+4a)/(4+4b)NSWER:(2+4a)/(4+4b)
