How many types of personal pronouns are there?

Words that replace nouns in a sentence are called pronouns. There are eight main categories of pronouns in your syllabus. Among them, personal pronouns are those pronouns that replace the name of a person or an object, and in this process make the sentence smaller. Now, the personal pronouns are used as the subject of the verb, we call them subjective cases, and when they are used as the object of the verb, we call them objective cases. Also, when personal pronouns indicate ownership or possession of something, we call them possessive cases. So, option B is the correct one.
