Need help with my copyright class, please. There's this question worth 2 points; I've already chosen a combination of answers and have still gotten them wrong. I cannot seem to get the answer right.

Question: To determine when a copyright expires which of these do you need to know? (check all that apply).

A) Author's date of birth

B) Date work was created

C) If it has a corporate author

D) Where it was published

E) If it was properly renewed

Really appreciate your help!
