Choose the word which is different from the rest.

The answer is B. Knight.

A nun is a woman who has dedicated her life to God and lives in a convent. A monk is a man who has dedicated his life to God and lives in a monastery. A priest is a man who has been ordained to perform religious ceremonies and rituals. A padre is a priest in the Catholic Church.

A knight is a man who is a member of the military and is skilled in the use of weapons. Knights are often associated with chivalry and the Crusades.

The word “knight” is different from the rest of the words in the list because it is the only word that does not refer to a religious figure.
