At end of the year, a company has a $1,200 debit balance in Manufacturing Overhead. The company:

(a) makes an adjusting entry by debiting Manufacturing Overhead Applied for $1,200 and crediting Manufacturing Overhead for $1,200.

(b) makes an adjusting entry by debiting Manufacturing Overhead Expense for $1,200 and crediting Manufacturing Overhead for $1,200.

(c) makes an adjusting entry by debiting Cost of Goods Sold for $1,200 and crediting Manufacturing Overhead for $1,200.

(d) makes no adjusting entry because differences between actual overhead and the amount applied are a normal part of job order costing and will average out over the next year.
