The rational approach is the approach to political science which assumes that individuals weigh the costs and benefits of each choice in order to maximize their benefits.

Explanation:

When an individual has a choice to make, he is most probably inclined towards choosing an option that offers more benefits at less cost. This is because the individual looks for the choice that pays him back with more than the worth of the cost that he is paying. This natural tendency of making an intelligent choice is a trait that is found in most individuals that are mentally sound.
