A corporation records a dividend-related liability
a. On the record date
b. On the payment date
c. When dividends are in arrears.
d. On the declaration date.

Thank you in advance for any help!

My feeling is that the answer is b: on the payment date...

It's a badly worded question, but if we pick it apart grammatically and throw out the adjective "dividend-related," then it's asking when to "record a liability." You don't record a liability when you pay it. You take it out of the liability when it's paid. Recording the liability is when the liability is first recorded. When would that be?
