Question

article iii. the said states hereby severally enter into a firm league of friendship with each other, for their common defense, the security of their liberties, and their mutual and general welfare, binding themselves to assist each other, against all force offered to, or attacks made upon them, or any of them, on account of religion, sovereignty, trade, or any other pretense whatever.
it emphasizes the strong and united central authority created by the sovereign states
it highlights the resentment of several states that were forced to join the alliance
it highlights the cooperation and collaboration between the sovereign states

Explanation:

The text describes states entering a league for common defense, security, and welfare, binding themselves to assist each other. This shows cooperation. The first option is incorrect as it's about a league, not a strong central authority. The second option is wrong as there's no mention of resentment or being forced.

Answer:

It highlights the cooperation and collaboration between the sovereign states.
