I vaguely recall that Require is used for checking conditions that shouldn't happen, but I need to double-check that.

I'm a bit confused by this question. I know require is important, but I'm not sure of the exact use case. I'll have to review my notes and try to reason through the options.

Okay, I've got this. Require is used to check for conditions that should never happen, like invalid internal states. That matches option A, so I'm going with that.

Hmm, this looks like a tricky concurrency question. I'll need to carefully consider the transaction isolation level and how the FOR UPDATE clause affects the locking behavior.
