Ships.
Sea transportation was just right at that time as it can carry loots, spoils of war , enough fire power to conquer new colonies, and also food and necessities for sojourners ,seafaring soldiers and traders. Even exploration of unknown territories was also done with the help of sea transportation.
I would say that you, as a Massachusetts farmer during the French and Indian war, oppose the Albany Plan of Union because you do not want to be closely tied to non-Puritans and Southern slave owners.
A is incorrect because this plan would actually centralize the defense. B is incorrect because the Crown of England rejected the plan. D is incorrect because who is Edward Albany? :S
The answer is B!
Hope it helps!
