why isn't this a brute force attack?

It's D, DDoS-ing is when you overload a webserver with traffic requests

The numerous computers from multiple geographic locations are sending a very high number of connection requests, which is causing the company’s web server to become unavailable to the general public. So, the correct answer is D. Distributed denial of service.

D is correct. Because DDoS is when an attacker send so many ping requests like DoS but there's more than one device. And when theres multiple computers that became zombies or botnets. Then the attacker including zombies, or bots sends too many ping requests that it decreases performance on the server itself making internet connections very slow.
