Answer:
The correct option is d.
Explanation:
It is given that $15,000 is considered to be material to the income statement, but $25,000 is material to the balance sheet.
Material to the income statement = $15,000
Material to the balance sheet = $25000
The auditor should set overall materiality according to the income statement.
The auditor should set overall materiality at $15,000.
Therefore the correct option is d.
