Question about Syntax in JavaScript

Check this out, this is from one of the quizzes:

What is a "syntax error"?

A   A logical mistake in your programming.
B   Forgetting to add a closing <script> tag to a web page.
C   A "grammatical" mistake like mistyping a JavaScript command or forgetting a closing parentheses or quote mark.
D   Using the wrong path when linking a JavaScript file to a web page.

The correct answer is C.

My question is, how come the correct answer is not B?

It because B is in HTML? Would that be an HTML syntax error? Or would this error be a different kind of error?

Thank you!

Can you provide link to the specific quiz? I expect there's something in the wording of how "syntax error" was defined that will distinguish the correct answer here.

script tags are found in HTML, and not in JavaScript. So in this case forgetting to close a script tag would be a syntax error in HTML and not in JavaScript.

I don't think that the missing tag would generate an error itself, the error would be reported when the browser tried to interpret the HTML code following the missing script tag as JavaScript. And the page would likely stop rendering at that point. I think Poly has this nailed down, you have to consider the context, and the script tags delineate the script from the HTML, so technically, the missing tag is more likely considered a mark-up error.
