the grandmother was against the teaching of music because she considered music a sublime b good for him c monopoly of harlot's and beggars

The correct answer is C. The grandmother was against the teaching of music because she considered music a monopoly of harlot's and beggars.

Explanation:

The question refers to the novel "The portrait of a lady", in which the narrator of the story moves with her grandmother to a rural area far from the city, and begins to go to school.

At school, the narrator begins to take music classes, which distresses and annoys her grandmother, who considers that music is not an art but a simple expression of social baseness, carried out by beggars and criminals, without any religious, moral or aesthetic content.
