Possibly A

In Verdi's early period, a librettist would be hired to write a set number of arias, duets, choruses and finales, following a (usually) well known story. Puccini on the other hand set existing stage plays or novels (by Sardou, Belasco, Murger) which had far more natural, real-life structures than the Verdi dramas.
