make it possible for foreign-owned factories to import components for assembly without customs duties.

The answer is B. Make it possible for foreign-owned factories to import components for assembly without customs duties.

Mexico’s Maquiladora program was started in the 1960’s. This program was initially set up the Mexican government to attract foreign companies to start their manufacturing in Mexico. It later emerged that the program wanted to attract foreign businesses, and to do so, the program offered tax benefits on imported goods that were used for their manufacturing process. Until today, assembly components, production equipment, and materials, under this program, are allowed to enter Mexico duty-free.
