Answer:
The correct option is a. $200 preferred; $19,800 common.
Step-by-step explanation:
These can be calculated as follows:
Dividends paid to preferred shareholders in 2015 = Number of outstanding shares of noncumulative preferred stock * Preferred stock par value * Dividend percentage of preferred stock = 400 * $10 * 5% = $200
Dividends paid to common shareholders in 2015 = Dividend declared and paid in 2015 - Dividends paid to preferred shareholders in 2015 = $20,000 - $200 = $19,800
Therefore, the correct option is a. $200 preferred; $19,800 common.
