Answer:
The correct answer is: Materials Price Variance: Production Manager
Materials Quantity Variance: Purchasing Agent
Explanation:
The production manager had to buy the materials that are commonly used, as this is an item of great importance in the process of converting the materials, since otherwise there is a risk of becoming waste due to their quality. In the case of the variation presented, each manager or person in charge of the area must supervise that the measurements are well calculated, and that the aspects related to the direct process must be effectively ensured for the good of the operation.
