Explanation:

First Question (What is the best thing to do if someone wants to use copyrighted work or materials?):

To use copyrighted work, the most proper action is to get permission from the copyright owner. "Fair Use" has specific legal criteria and isn't a default claim. Citing/referencing is for attribution but doesn't grant usage rights without permission.

Copyright ownership duration is typically the life of the author plus 70 years (this is a standard copyright term in many jurisdictions, like the US and under Berne Convention principles). 70 years alone, life + 50, or 100 years don't match standard copyright law.

Answer:

B. Ask permission from the copyright owner
