The answer is A. delegating authority. hope it helps :)
Answer:
"The Articles of Confederation introduced thirteen different articles that granted powers to the states and to the federal government. ... Each state retains its sovereignty, freedom, and independence, and every power, jurisdiction, and right, which is not by this Confederation expressly delegated."
Explanation:
Enumerated powers are enumerated in some kind of document.
Implied powers are not specifically enumerated in some kind of document, but they would be necessary to fulfill some responsibility.
I'd say it would be speaker 4 since it mentions a specific interest like you said
