Answer: A. decrease stockholder's equity and increase liabilities
Step-by-step explanation:
When Stock is declared, the relevant entries include;
DR Retained Earnings
CR Dividends Payable
Retained Earnings is an Equity account that the dividends will be taken from and will reduce as a result. This is why it is being debited.
Dividends Payable is a liability account that will be credited to show that the company owes its shareholders dividends. Liabilities will therefore increase.
