Final answer:
When working with a CMT factory, a sourcing firm is tasked with providing the patterns, specifications, and sample garments needed for production, paralleling the responsibilities within a costume shop. Option number a is correct.
Step-by-step explanation:
When contracting with a CMT (Cut, Make, and Trim) factory, a sourcing firm is responsible for supplying patterns, specifications, and sample garments. In the context of a costume shop, the Costume Shop Manager or Supervisor oversees budgets and supply inventory while a Cutter\/Draper creates patterns using actor measurements.
A First Hand cuts out the new pattern, and a Stitcher assembles the costume. This parallels the process with CMT, where the sourcing firm provides the essential instructions and components, minus the fabric, for the CMT factory to assemble the product.
