I've answered those sorts of surveys before and fwiw I always interpreted that question differently. It's not "is YOUR best friend a coworker" but instead "do you have A best friend at work" which should be true of anyone who has at least one friend at work (using friend in a fairly loose sense). I can't say I've ever had a long-lasting friendship with a co-worker but at every job I've ever had I had people I worked with that I considered friends. Even if you don't do stuff outside of work together you still spend more time with your coworkers than almost anyone else. And if you develop a relationship with your teammates where you can speak to each other frankly and trust one another's good intentions then that makes for an infinitely better work environment even if you don't generally discuss personal matters. Whether or not that counts as "friendship" is a matter of semantics but I think it is the sort of relationship that the question is asking about.
