Here's how you can translate "whom" depending on the sentence:
* "Kisne" - When asking who did something or who is responsible for something. Example: "Whom did you meet?" - "Aapne kisne mulaqat ki?"
* "Kisko" - When asking who something was given to or done to. Example: "Whom did you give the book to?" - "Aapne kitab kisko di?"
* "Kiske" - When asking who something belongs to or is related to. Example: "Whom does this house belong to?" - "Yeh ghar kiske hai?"
Remember, the correct Hindi translation will depend on the context of the sentence.
