A segment of a business responsible for both revenues and expenses would be called:

A) a cost center.
B) an investment center.
C) a profit center.
D) residual income.

A profit center is responsible for generating revenues and also has control over its expenses, as opposed to a cost center which is responsible only for controlling expenses, and an investment center which is responsible for generating profits from invested capital. Residual income is a measure of the profits earned above a required minimum return on investment, but it does not refer to a specific business segment.
