Is the integer N odd?
(1) N is divisible by 3
(2)2N is divisible by twice as many positive integer as N.
Per following link:

Answer is B. But I disagree. Here is why:
if you pick 9 or 18 logic adds up. but if you pick lets say 17 then 2(17) doesn't have twice as many divisors as 17 has.
am I looking at it the wrong way or is the answer really is E.
thanks
