Answer: a. retained earnings was overstated and liabilities were understated.
Step-by-step explanation:
Dividends are paid from the Retained Earnings so when a company announces a dividend, that dividend is to be deducted from the Retained earnings. As this was not done, the Retained earnings at year end are overstated.
As the dividends are not paid immediately, they become liabilities. With the relevant entries not made, the dividends were not recorded as liabilities which makes liabilities understated.
