Final answer:
The manager or supervisor of a responsibility center is in the best position to see how funds are being expended.
Step-by-step explanation:
The person within a responsibility center who is in the best position to see how funds are being expended is the manager or supervisor of that center.
The responsibility center is a unit within an organization that is given the authority to make decisions and incur expenses. The manager or supervisor of the responsibility center is responsible for monitoring and managing the center's budget and expenditures.
For example, in a retail store, the store manager is in the best position to see how funds are being expended in their responsibility center, which is the store itself. They are responsible for tracking sales, monitoring expenses, and making decisions about hiring, inventory, and other expenditures.
