Master production schedule, bill of material, and inventory data

Explanation:

The Material Requirements Plan (MRP) is an analysis that lists the material/components needed in order to produce something.

First, you need to take into account the material needed, then the inventory you currently have then plan the acquisition of the material for the production to continue.

Answer A talks about payroll, that has nothing to do with the MRP.

Answer B talks about capacity plan, that has nothing to do with the MRP.

Answer C talks about suppliers list, that's related but not precisely part of the MRP.
