What do I say if the professor says no to an extension?
Thank the professor, ask which alternative can be approved, and put the answer in writing — a refusal is still information you can use.

The useful follow-up is a question about scope, not a second argument: a shorter delay, a late submission with the penalty named, or credit for finished sections.
A refusal usually comes with a reason you can reuse: a marking schedule, fairness to the class, or a rule the instructor cannot bend. That reason is the only thing worth quoting if you later ask the same question of a course coordinator or an adviser, and it tells you how the rest of the assessment will be judged. Then put the decision in your calendar as a real deadline and split the remaining work into two sittings, because a refused request costs you the days you spent waiting.
