-----told you to come here?

Ans: Who told you to come here?

The question '-----told you to come here?' can be transformed into a grammatically correct sentence by inserting the appropriate interrogative pronoun. Let's examine the potential options: 1. Who: This is an interrogative pronoun used to ask about which person is the subject of the verb. In the context of the sentence, "Who told you to come here?" correctly implies asking for the identity of the person who gave the direction to come. According to the Oxford English Dictionary, "who" is used when inquiring about a subject that performs an action (source: Oxford English Dictionary). 2. Whom: This pronoun is used to ask about the object of the verb or preposition. Since the sentence in question looks for the subject performing the action, "Whom told you to come here?" would be incorrect. "Whom" would fit into a sentence like "To whom should I address the letter?" where it is the object of the preposition "to" (source: Merriam-Webster). 3. What: This is used to inquire about things, objects, or non-living subjects. The sentence "What told you to come here?" would suggest a non-living entity is being referred to, which doesn't fit the context provided by the question, as we typically seek a person not an object or idea (source: Collins English Dictionary). 4. Which: This pronoun is used to ask about a specific item or person from a known, limited set. For example, "Which book are you reading?" In the context of the given question, there is no indication of a limited set of options from which we are asking about the identity, making "Which told you to come here?" incorrect (source: Cambridge Dictionary). Given these analyses, the correct answer to the question '-----told you to come here?' is "Who". It properly inquires about the person who gave the direction, aligning with proper grammatical structure and the recognized use outlined in authoritative sources. This forms a coherent and grammatically sound question: "Who told you to come here?"
