Final answer:
Borrowing through bonds is the low-risk finance option for a company among the three main ways to finance an asset purchase.
Step-by-step explanation:
The low risk finance option for a company among the three main ways to finance an asset purchase is borrowing through bonds. Government bonds, such as those issued by the U.S. government, are considered low-risk because the government is extremely likely to pay off the bond, albeit at a low rate of interest. Bonds are assets for banks as they will receive a stream of payments in the future.
