A potential benefit for a government leader using a cost benefit analysis is?

I'd go mostly with B.

Explanation:

Whenever you want to present goals (That includes political goals like passing bills into law, getting the Approval of thy fellow Government & your people) No matter what, it'll always get negative proving from either side.

So what they do to likely increase support, and hopefully decrease disapproval is to present a cost-benefit analysis to a Congress/Parliament so they can show that not only will it benefit their agenda & their nation, but it would also help the Nation's treasury better too.

I would have said C, That one of the Government's primary concerns is not spending (Esp. the United States).

Everything is about Politics when you are in Politics, Including the things that you own & enjoy.

Hope this helps!

the answer is hope this you.
