What best describes why investing can be such a chalange

c) There are no guaranteed investments.

Explanation:

Although all statements are mostly true, the c) answer describes the challenge of investing in the simplest way possible.

The guarantee of investments is not discrete, meaning an investment can never be 100% or 0% guaranteed. Investments are always associated with a certain amount of risk, as numerous factors are always influencing its outcome. Therefore, we can differ only high-risk, low-risk and medium-risk investments.
