Pick the correct sentence.

Pronouns are words utilised in place of nouns. They can only be used once the noun is used or mentioned. Pronouns are of several types, such as personal, reflexive, emphasising, relative, demonstrative, indefinite, interrogative, and possessive. Relative pronouns are used to show the relationship to a noun mentioned in the sentence earlier. Examples of relative pronouns include “that,” “which,” “where,” “whose,” “whom,” and so on. “That” and “which” are usually used for non-living entities, and “whom” is an objective pronoun. So, the correct way to frame the sentence is, “People who exercise daily remain healthy.”
