a. permitted to sell raw materials and finished goods.
b. not permitted to find and sell raw materials.
c. not permitted to manufacture many finished goods.
d. permitted to buy raw materials and finished goods

c. not permitted to manufacture many finished goods.

Explanation:

The British required raw materials so as to make items in their manufacturing plants in Great Britain. It was less expensive for the British to set up colonies and get the raw materials from those settlements than it was for the British to purchase those raw materials from other nations. When the British got the crude materials, they made items that they could then sell to the colonies.  

In this manner, by having colonies, the British had an ensured market for the items that were made in their production lines. This helped Great Britain's economy, and it helped Great Britain benefit from having the colonies.
