Painless Orthodontia Is Located in One Corner of the Second

Painless Orthodontia is located in one corner of the second story of Beazley Department Store. Painless patients have access through an outdoor stairwell, but there is an indoor hallway on the second story, near the billing and credit department of Beazley's store. Beazley saw some benefit in having parents and patients going through the store on the way to appointments and as a way to have parents waiting for children at appointment to do some shopping. Beazley Department store's CEO wrote on its letterhead, "Beazley hereby grants Painless Orthodontia the right to use the hallway on the second floor of Beazley's building as long as the said room remains unpartioned [sic] by brick and continuous through to the roof." Beazley:

A) Has granted a profit.
B) Has granted an express easement by reservation.
C) Has granted an express easement by grant.
D) Cannot convey a portion of its building.
