Answer:
b. An income statement account,
Explanation:
The allowance for doubtful debts accounts is not an income statement account because it has not yet been regarded as a bad debt expense which would be shown in the income statement as an expense.
It is a contra asset account that would be deducted from the asset it relates to in the balance sheet(the accounts receivable)
So also, it is an estimate of the uncollectible portion of the accounts receivable.
Finally, the fact it is reflected in the balance sheet means it is a balance sheet account.
