After what or whom was Vincenzo Bellini's opera "Norma" named?

The opera composer Vincenzo Bellini (1801 –1835) was born in Catania, Sicily and was sometimes known as “the Swan of Catania.” His work was hugely influential; Giuseppe Verdi acknowledged Bellini’s technique, and other music composers such as Wagner, Liszt and Chopin were admirers. Bellini’s “Norma,” first performed at La Scala opera house, Milan in 1831, is widely regarded as a leading example of the “bel canto” genre.

Each of the answer options has a connection with the opera.

-- “Pasta alla Norma” was named after the opera (not the other way round). This is reputed to have happened in a Catania restaurant when the local writer Nino Martoglio (1870-1921) compared a perfect example of the dish to Bellini’s masterpiece.

-- Giuditta Pasta (1797 –1865) was the star soprano who performed in “Norma” on its opening night.

-- The French poet Alexandre Soumet (1788 –1845) wrote the tragedy “Norma, or The Infanticide” after which Bellini’s opera was named and which provided the basis for the opera’s libretto.

-- The Norwegian playwright Henrik Ibsen (1828 –1906) wrote the political drama “Norma, or A Politician's Love” based on Bellini’s “Norma,” which he had seen performed in 1851.

This makes Ibsen’s work a Norwegian drama based on an Italian opera based on a French tragedy.
