Same here, are you sure it isn't a^(2b+1) for answer choice [E].

If so, [C] is the answer as stated above.

I think C either can be or can not be. So C should eliminated

E can not be even!

Odd number divided by even number cannot be even.

Sorry, to clarify...

even / odd = even
odd / odd = odd
even / even = odd or even
odd / even = non-integer

Still curious about how answer [E] was initially typed in... JCLEONES?

can someone put an example where C cannot be the answer ? Last time I checked , odd/even will never be an integer.
