The correct answer is letter C.
Pope Innocent II suffered the strong opposition of Anacleto II and had to flee and take refuge in France, where he won the support of the King of England and Emperor Lotharus II. Supported by a Saxon army, Innocent II defeated soldiers supporting Anacleto II and returned to Rome eight years after his election in 1138 with the death of Anacleto II and the resignation of his successor, Victor IV.
