A) What is stress relieved with?
- This sentence is incorrect because we need to use the active form of the verb "relieve".

B) What does relieve our stress?
- This sentence is correct because it uses the present simple tense with the auxiliary verb "does" to ask about the subject that relieves our stress.

C) What relieves our stress?
