Of the following different types of securities, which is typically considered most risky?

a) Certificates of deposit

b) Long term government bonds

c) common stocks of large companies

d) U.S. treasury bills

Cannot seem to find the answer anywhere, I am hoping someone out there will know this, any and all help is appreciated.

I would say it is C but not real sure

I agree with Demonspeeding_2005

c) common stocks of large companies, I think would be the most risky.
