What is the most effective way for Congress to prevent a president's foreign policy? cut off budget support for that policy pass a resolution against that policy rally public opinion against that policy refuse to ratify a treaty Is it A?

Answer 1

In general, the most effective way for Congress to prevent a president's foreign policy would be "cut off budget support for that policy" since Congress needs to approve funding. The President could still issue an executive order, however.

Answer 2

The correct answer is cut off budget support for that policy

It is very simple, the congress has to approve budget allocations for various presidential policies. If they dislike what the president is doing, they can just cut off the budget and the president can't do anything about it. For example, if the president supports humanitarian work in another country and the congress things that the money could be better spent, they could prevent him from getting money which would end the humanitarian help.
