D. the president's role in foreign policy had not yet been specifically defined.
Explanation:
The Constitution does not explicitly state that the President has sole authority over foreign policy, and so at this point in history it was still unclear exactly how much power the President actually had in regards to international affairs. Washington didn't want to take a position on such a contentious issue without knowing for sure that he could back up his stance with actual authority.
I think the bake sale would be better because, if one we're to do a car wash they may not know how to wash a car and selling baked goods is WAY easier than a car wash. A car wash can be bad depending on the weather and the bake sale. So I would chose the bake sale, it's easier, faster and much more.
