* Whom: Used for objects of verbs or prepositions (Whom did you call?)
* Whose: Used to show possession (Whose book is this?)
* What: Used for things or actions (What is your favorite color? What are you doing?)
* Which: Used for choice (Which one do you prefer?)
* Why: Used to ask for a reason (Why are you late?)
* Where: Used to ask for a location (Where is the library?)
