Select one:

c. The commercial loans have a higher systematic default risk and thus lower benefit of diversification.

d. The real estate loans have a higher systematic default risk and thus lower benefit of diversification.

e. The real estate loans have a higher systematic default risk and thus higher benefit of diversification.
