Answer:
c) $7200
Explanation:
Preference dividends have preference when it comes to payment of dividends.
This means that we pay the Preference Stock holders their dividend (which is fixed) and there after the remainder is paid up to the Common Stockholders
Preference dividend = 900 shares x $100 x 4 % = $3600
When Preference Stock is Cumulative, it means that all previous dividends in arrears have to be paid up before any current year distributions are made.
2018
Cumulative Preference dividend = $3600 (2017) + $3600 (2018) = $7200
therefore,
Dividends in arrears at December 31, 2018 total $7200
