The correct answer is letter "D": Traceable to a single cost object.

Explanation:

Direct Cost for finished goods is referred to the costs of the items and services directly used in production that can be allocated to a single cost object. Other costs including rent and production site insurance are indirect costs. The cost of the finished goods may be assigned to indirect costs, but they are not direct costs because they do not change with production levels.
