The correct answer is C. Mercenary.
A mercenary is a professional soldier who fights for money, not for patriotism or any other cause. They are often hired by governments or other organizations to fight in wars or other conflicts. Mercenaries are not considered to be courageous or patriotic because they are not fighting for a cause that they believe in. They are simply fighting for money.
A sinecure is a position that pays well but requires little or no work. An honorary position is a position that is given as an honor, but does not come with any real power or responsibility. An equestrian is a person who owns horses.
