Vincent Was a Wealthy Widower Who Owned Some Very Valuable

Vincent was a wealthy widower who owned some very valuable paintings. Four years ago, Vincent promised to give an original Picasso painting to Bela, his butler, in return for many years of service. However, three months ago, Vincent dismissed Bela from his service, following a major disagreement and vowed never to have contact with Bela again. Vincent died yesterday from a heart attack. Bela remains executor of Vincent's will. Bela:

A) Is not entitled to the Picasso painting, as Vincent did not complete an inter vivos gift to Bela.
B) May be entitled to the Picasso painting, as he entered into an agreement with Bela, which Bela can now enforce as executor of the will.
C) Is not entitled to the Picasso painting, as Vincent clearly changed his wishes following the major disagreement with Bela.
D) May be entitled to the Picasso painting, as the gift is completed by Bela getting legal title to the property as executor.
