A characteristic of solar loans that makes them attractive to potential solar ABS investors is their:

选项：

A.

universal availability to any homeowners.

B.

ability to combine multiple liens to mitigate default risk.

C.

flexibility in allowing either purchase or rental of solar systems.

解释：

The correct answer is B. Default risk minimization adds to investment appeal, and solar loans provide opportunities for overcollateralization. Normally, solar ABS are collateralized by the underlying debt: mortgages, loans, or receivables. These loans can be further collateralized by a lien pledged on the installed systems, on the property itself, or both.

A is incorrect as solar loans are typically extended only to prime borrowers who own their homes and have good payment records.

C is incorrect as the loans enable property owner purchase of installed systems instead of rental that is transacted through solar leases.
