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: He was engaged in a series of amorous episodes with women in Nadezhda von Meck's large household, which caused her to become markedly cold towards him.

He had also contracted syphilis. After _his_ dismissal by Nadezhda von Meck, Kotek went to Berlin to study with Joseph Joachim. <sep>, Pronoun: his <sep>, A: Kotek <sep>, B: Joseph Joachim
Output:
A
