The swiss family robinson why is the ship well equipped for the robinsons' adventures on the island? a. the ship contains the robinsons' belongings, which are all the family needs. b. the ship is full of goods the captain planned to sell, which the family takes. c. the sailors' belongings include everything the family needs. d. the ship carries supplies for starting a new colony and are useful for the family.

D. The ship carries supplies for starting a new colony and are useful for the family.

Even though the ship carries the belongings of the family, those things would be considered trivial and not very vital for survival.  Even goods that were intended to be sold would not be as important to supplies for starting a new colony because supplies that were intended to be used to begin a new colony would have been intended for the use by those who would have been away from civilization and needed to be self-reliant as the Swiss Family Robinson becomes after the shipwreck.
