Answer:
Option C Liabilities are overstated
Explanation:
Option A is incorrect because the double entry posted is equal in credit and debit so the the equation will hold true.
Option B is also incorrect because the double entry does not includes the expense account then how it is overstated.
Option C is correct because the entry has overstated the payables by incorrectly crediting the account payables instead of trade receivables.
Option D is also incorrect because the entry passed in the cash account is correct because when cash is received it is always debited so it is not overstated.
