Answer:
D. Both pronouns are indefinite.
Step-by-step explanation:
Pronouns are parts of speech used to replace nouns. In English, there are several types of pronouns: personal, demonstrative, interrogative, reflexive, reflexive, indefinite.
Now, let us just briefly explain the ones mentioned in the options.
Personal pronouns refer to persons (I, you, he, she, it, we, they).
Demonstrative pronouns are used when we point at something (this, that, these, those)
Indefinite pronouns, as the name suggests, refer to people or things but without precisely naming them (anyone, everybody, no one, somebody etc.).
So, with this in mind, we can now see that "some" and "no one" don't exactly name things, which makes them indefinite.
