Answer:
b. federally mandated environmental project
Step-by-step explanation:
Based on the options provided the investment with the least amount of risk would be a federally mandated environmental project. This is because it is a project that is backed by a government, which tend to have contingencies in place to prevent failure. While a new product has not previous historical data that would reduce the risk, it is unpredictable what will occur once it gets released into the market, and is all speculation, thus it has a very high risk to it.
