Man this question would sink me because of the misnomer that HTML is a programming language.

I would loudly go on the record for my reasoning that Hypertext Markup Language is not Turing Complete, and therefore fails to be a programming language by the only academic and theoretical definition that matters.

They already are going to award me “lawyer up” money, so I’ll come after them for damages later if B is the "right’ answer.

wrong again! CSS is turing complete, and HTML can include inline CSS, so you can implement a Turing machine in HTML only (without external .js files)

It can also include inline JS. HTML alone cannot be turing complete, but HTML+CSS is.

CSS can be included as a style property without requiring the script/style tag though.
