The correct answer is
<span>The colonies developed an ability for self-governing
Basically, the salutary neglect was a policy where the British parliament made laws but didn't enforce them in the colonies. This was meant to help keep the support of the colonists. They governed themselves and this is another reason why the intolerable acts were intolerable. </span>
Most Americans supported isolationism. They didn't want to engage in another European war. Although this agreement didn't include sending troops to Europe, it involved sending 50 destroyers to UK, so the amount of help was rather major.
I would say <span>B) Great Britain
