I'm sorry, but I don't have enough information to answer your question. The question "What is her favorite subject?" is quite vague and doesn't provide any context about who "her" refers to. In order to provide a detailed answer, I would need more information, such as the name of the person you're asking about and any relevant context about their interests or academic background.

If you can provide more details, I'd be happy to help answer your question in a more specific and detailed manner.
