Answer A is music to our ears. "Maestro" means "master" in Italian, coming from a Latin word with the same meaning. It usually refers to someone who has studied for a long time and has become not just an accomplished performer, but is usually also a top-notch teacher, composer, or conductor. "Virtuoso" is also Italian, coming from an adjective with the same spelling that means "virtuous" or "skilled." It traces back to the Latin word "virtus," meaning "strength" or "virtue." "Virtuoso" usually refers to someone who has studied to become an outstanding performer and excels in the technique of playing an instrument.
