D."This means the products were made in fair working conditions and the companies/producers did not use child labor."
Step-by-step explanation:
Fair trade production means commodities are produces in the fair social and environmental standards.
The fair-trade agreement is made to guarantee the production in developing countries betters the conditions and doesn't damage the social conditions and environment.
