To the best of my knowledge none of the books about Harry Potter are called "Harry Potter". You could write "Harry Potter and The Philosopher's Stone" is my favourite (BrE) book", for example.

If you're writing them, book titles should be put in inverted commas.

If you're typing them, and have the facility to put them in italics - as we do - then do so.

Hello.

Thank you for a nice question.

Rover_KE, so option C is correct, isn't it? And the italic font can be leave out.

Thanks,

Alex

He is saying if you can use italics, then use italics. If you are writing by hand, or are using unformatted text (like simple email), then use quotation marks (" ").
