Explanation:

• Option A (Incorrect): A value-added reseller not only distributes a product but also handles more complex aspects such as installation, customization, or support. This does not align with the description of a company that solely produces goods for others to market.

• Option B (Incorrect): A licensing arrangement involves producing a product under someone else's brand name in return for a royalty. This is not the same as producing goods for other firms to market under their own branding.

• Option C (Correct): A contract manufacturer is a company that produces goods specifically to be marketed by other firms, which matches the description provided in the question.
