grammer?, which is correct? Options

[jayi12-15psi]

Hey guys, I know this isn't the most exciting topic, but I was wondering if you could help me out. In the sentance below, is it correct grammer to use the apostophe in it's, or is it correct to leave it out in this instance.

Word is correcting me, but I was curious if I was wrong or not. I mean, the obstacles are technically the "property" of the rational choice theory.

On various occasions, combined rational thinkers use social capital to achieve great results, however rational choice is not without it’s obstacles.


Thanks guys and girls.

im pretty sure "its" is correct because it shows possession of a singular noun (choice)

rational choice is not without its obstacles.


excerp from above link:
wrong: The group made it's decision.
correct: The group made its decision.


this is how it should be if it is plural possession:

choices are not without their obstacles.

if you really want to be on the safe side just remove it completely

rational choice is not without obstacles.

or say

rational choice is not free of obstacles.
