Which motivation was the most important for european colonization of centra america a. converting africans to christianity b. exploiting the colonies for profit c. understanding native african culture d. spreading european culture

I believe the answer is:

B. Exploiting the colonies for profit 
(the central American region was known for various agricultural commodities that are popular in European continent such as their coffee beans, tropical fruits, latex, etc.
By colonizing the central American region, the british could obtain these commodities at cheaper prices and obtain higher profit from other European countries)
