Intransitive verb

So you cannot debate me?

I thought about " debate with you") but, yes, you gave me clue, thank you)))
What question can I put for the verb to make it transitive - debate what about? Debate about? Debate with whom? Or debate whom?

You can debate any challenger you have..

One can debate an issue. Any dictionary will provide examples.

But what about this example: The students debated which novel they should read or The students debated what book to choose for the next class?
Do I understand this correct that they debate What about? Debate about book choice. Is this verb in the given sentence transitive or intransitive?
