Final answer:
A government bond fund is recommended for preservation of capital and a moderate income stream for an elderly client.
Step-by-step explanation:

A government bond fund consists of a portfolio of government bonds issued by the federal government or its agencies. These bonds are considered low-risk investments because the government is virtually certain to pay off the bond. The fund provides a stable income stream in the form of regular interest payments from the bond holdings.By investing in a government bond fund, your elderly client can preserve her capital and receive a moderate income stream without the need for active management of individual investments.
