Answer:
The correct answer is simply option A.
Step-by-step explanation:
Total stockholders' equity comprises retained earnings (accumulated net profit or loss over the years minus dividends), common stock and premium.
Common stock dividend is simply dividend paid to the owners of common stock from the retained earnings of the company. This could be in form of cash or dividends.
Before the issue of the common stock dividend, the company's common stock value was 207,000 shares of $1 par value, that is $207,000. 10% common stock dividend at $23 per share on May 1, 2021 translates to 0.1 x 207,000 shares x $23 = $476,100. Since it was common stock dividend, the total stockholders' equity would increase by $476,100. If it was a cash dividend, it would have decreased by $476,100.
