A lease is where you arrange to use someone else's property, generally in exchange for money. The ownership of the property remains with the other entity. So with that in mind, let's look at the options.  
A. A contract outlining the terms of a mortgage.  
* This is a contract arranging for the transfer of ownership of property from one entity to another. So this is not a lease and is a bad choice.  
B. A contract outlining the terms under which a landlord agrees to rent property to a tenant.  
* This does meet the definition of a lease. You rent and therefore use someone else's property, but the ownership of the property remains with the landlord. So this is the correct choice.  
C. A loan from a bank used to rent a home. 
 * This does not meet the definition of a lease and is therefore a bad choice. 
 D. A loan from a bank used to buy a house. 
* This also does not meet the definition of a lease and is therefore a bad choice.
