So, (1) is NOT SUFFICIENT to answer the question.

(2) n/45 is an integer implies n should be multiple of 45, which lies between 100 and 200. The possible values are 135, 180. But 180 is the only even integer.
So, (2) is SUFFICIENT to answer the question.

The correct answer is (B).

We are asked for the value of n.

We know that n is an integer between 100 and 200 exclusive.

(1) n/36 is an odd integer

When n is divided by 36, the result is an odd integer. Or:

n/36 = odd, or:

n = 36*odd

Because n has to be between 100 and 200, n could be:

n = 36*3 = 108 or n = 36*5 = 180

Because n can be either 108 or 180, (1) is insufficient.

(2) n/45 is an even integer

So:

n = 45*Even, and in order to confine n within the restricted range, it has to be: n = 45*4 = 180. Thus, (2) is sufficient.

Choose B.

thanks, i see what you are saying, sorry. how come the book says the answer is C?
