what is the term for a man who possesses both the high range of a woman's voice and the physical power of a man's voice?                 a.  libretto      b.  aria      c.  baritone      d.  castrato

The correct answer is D. Castrato

Libretto and Aria are not ways of singing but rather the types of compositions. Castrato is the way of singing where men can sing high pitched notes like women commonly do.  This is related to the prepubescent period of life before voice maturation occurs which is why many church choirs have young male singers because their voices haven't yet matured.
