Given the task definition, example input & output, solve the new input case.
In this task, you will be presented with a text, a pronoun from the text, and two candidate names. You should determine what the pronoun refers to and classify the answers into A, B, or Neither. A and B here are referring to option A and option B. Position of the pronoun in the text is showed within two "_"s.
Example: He grew up in Evanston, Illinois the second oldest of five children including his brothers, Fred and Gordon and sisters, Marge (Peppy) and Marilyn. His high school days were spent at New Trier High School in Winnetka, Illinois. MacKenzie studied with Bernard Leach from 1949 to 1952. _His_ simple, wheel-thrown functional pottery is heavily influenced by the oriental aesthetic of Shoji Hamada and Kanjiro Kawai. <sep>, Pronoun: His <sep>, A: MacKenzie <sep>, B: Bernard Leach
Output: A
Based on the text, his refers to MacKenzie so option A is correct.

New input case for you: Despenser's ruthless expansion of the de Clare lordship of Glamorgan in Wales led directly to the troubles of Edward II's later reign, including a rebellion in the Welsh Marches, the defeat of the Earl of Lancaster at the Battle of Boroughbridge, and eventually the deposition of the king by Roger Mortimer and Queen Isabella in 1326. Gilbert de Clare was the son of Gilbert de Clare, 7th Earl of Gloucester, -- known as Gilbert 'the Red' -- who in 1290 married Joan of Acre, daughter of Edward I. As a condition for the marriage, the earl had to surrender all _his_ lands to the king, only to have them returned jointly to himself and his wife for the lifetime of either. <sep>, Pronoun: his <sep>, A: Gilbert <sep>, B: Edward I.
Output:
A
