Answer:
Correct option is (C)
Step-by-step explanation:
There are some receivables that are likely to be uncollectible. These are called bad debts. An allowance for bad debts account is created as a reserve that is deducted from accounts receivables to show true value of accounts receivables, called net realizable value in the balance sheet.
When a receivable is written off, that is it is uncollectible, then this amount is reduced from both accounts receivable and allowance for bad debts account.
As such, write off of a receivable reduces allowance for bad debts.
