Which of the following would be the best allocation base for the Assembly activity? A. Direct labor hours hours B. Number of orders shipped C. Number of inspections D. Number of product lines

The best allocation base for assembling activities costs are the number of parts actually assembled.

Since the number of parts is not an option int his question, the second best allocation base for the assembling process is A) direct labor hours.

If the process is highly automated, then the second best allocation base would be machine hours, but that isn't an option either.
