I am also in the Univ. of Phoenix class. What is the answer to this question?

The question doesn't ask you about YIELD TO MATURITY (YTM). The YTM has nothing to do with this question. The question is theory based question wherein you have to write the characteristics of every instruments available in market. Hopefully tell me major instrumens which are covered by your course. Then I may help you a bit.
