Answer:
B) GNMAs are considered to be the riskiest of the agency issues
Step-by-step explanation:
The Ginnie Mae or GNMA pass through securities are mortgage backed. The Great recession taught us that mortgage backed securities are not always 100% secure, but they are still considered secure investments basically because they are guaranteed by the US government. They are similar to the securities sold by the US Treasury.
Ginnie Mae basically guarantees mortgages using federal funds (from Federal Housing Administration and Department of Veterans Affairs).
