Answer:
e. under-applied by $4,000
Explanation:
The overhead rate was calcualte considering labor cost:

144,000 / 240,000 = 0.60
Each dollar of labor cost applies 60 cent of overhead
applied overhead:
$220,000 labor cost x 0-60 each = 132,000 applied overhead
now we compare against the 136,000 actual overhead
as we didn't met the value and fell short, we have underapplied the overhead.

Trade credit allows businesses to receive goods or services in exchange for a promise to pay the supplier within a set amount of time. New businesses often have trouble securing financing from traditional lenders; buying inventory, for example, on trade credit helps increase their purchasing power.
