According to the textbook, the fact that one can buy a T-shirt for $5 in the United States is due primarily to

a. consumer demand for $5 T-shirts.
b. marketing strategies of large apparel companies.
c. the accessibility of cheap cotton.
d. lack of concern for the workers who make T-shirts.

Incomplete question. However it is inferred that question can be answered generally speaking.

c. the accessibility of cheap cotton.

Explanation:

Remember, selling price is a function of cost. Therefore, a $5 T-shirt may to a very large extent be affordable by most persons in the United States, because of the accessibility of cheap cotton in the country.

This access to cheaper raw material may increase the number of manufacturers in the country; resulting in a fair price for T-shirts due to competition among manufacturers.
