Answer:
B) Overhead costs were higher than expected or less labor hours were worked than expected.
Step-by-step explanation:
When using the direct labour hours to allocate cost, the overhead rate is calculated by dividing estimated overhead cost for a period by the estimated activity for that period.
The base that is estimated activity, is in direct labour hours, direct labour cost, or machine hours.
For Sable company to have an excess overhead it means in this ratio either the numerator is higher than estimated, or the denominator is less than expected.
The option that fulfils this is - Overhead costs were higher than expected or less labor hours were worked than expected.
The overhead cost were underestimated by the company.
