I'm leaning towards B, but I'll double-check the PHP documentation just to be sure. Can't afford to get this one wrong!

Haha, I bet the webserver using 'preemptive mode' is just a made-up answer choice to confuse us. Nice try, exam writers!

Wait, isn't the correct answer A? I thought headers_sent() returns true when you've already sent headers.

That's right. It's important to check if headers have been sent before trying to set them.

I'm not sure, but I think headers_sent() returning true would also allow setting headers after content is echoed.

I agree with Audrie, because output buffering allows headers to be set after content is echoed.

I think it's B. Output buffering needs to be enabled to set headers after content has been echoed.
