Castilian dialect, Spanish Castellano, a dialect of the Spanish language (q.v.), the basis of modern standard Spanish. Originally the local dialect of Cantabria in north central Spain, Castilian spread to Castile. After the merger of the kingdoms of Castile, Leon, and Aragon in the late 15th century, it became the standard language of all Spain and in the following centuries the language also of Spanish America.
Assuming this is in the present tense, the correct answer would be B, "bebe". You can deduce this because Ella is the person doing the action. So the verb must be in the el/ella/usted form. Since the verb beber ends with "-er" conjugating this verb into el/ella/usted form requires to take off the "-er" ending and add "e". Hence, "bebe".
