Final answer:
The type of lease most commonly found in retail business is B. Percentage Lease.
Step-by-step explanation:
This lease agreement involves a retailer paying a base rent plus a percentage of the revenue earned while occupying the space. This means that the rent varies according to the sales of the store. It is a popular choice for retail businesses because it allows both the landlord and tenant to benefit from the success of the business; the landlord receives a portion of the sales, providing an incentive to help facilitate the tenant's business success.
Other types of leases like Index Lease adjust rent based on a specified index, such as the consumer price index. A Graduated Lease has rent increases on a predetermined basis. In contrast, a Gross Lease typically involves the tenant paying a flat rent while the landlord covers the property expenses.
