Use of activity-based costing will result in the development of:
a. one overhead rate based on direct labor hours.
b. no overhead rates; overhead rates are not used in activity-based costing.
c. one plantwide activity-based overhead rate.
d. multiple activity-based overhead rates.

Option D Multiple activity-based overhead rates.

This is the reason why the activity based costing is critized for complex and time consuming method however nowadays this issue is resolved because of management accounting softwares.

So option A, B and C are incorrect because they say that activity based costing gives only one overhead rate  which is not true and is the characteristic of absorption costing.

u = 30

continuing your method

= +

= - thus

= -

= ⇒ u = 30
