Step-by-step explanation:
A reflexive pronoun is a personal pronoun having a form of self as a suffix that shows that the subject's action affects the subject itself. It is usually employed when the subject is the same person acting in the object.
On the other hand, a preposition is a word used to connect the following noun or a pronoun, in an adjectival or adverbial sense.
Take, for example;
He washed it himself.
Here, he is the sentence subject, and it is the preposition's object.
Indefinite pronouns are pronouns that do not usually specify the identity of its referent. Examples include anything, anyone, something, etc.
Interrogative pronouns are pronouns used in a question. They are what, which, who, whom, and whose.
