I'm a little confused by the wording of these options. Are they all valid acceptance criteria, just for different usability aspects? I'll have to read through them again carefully to make sure I'm choosing the right one for operability.

Okay, I've got this. Operability is about how well users can actually complete tasks, so the correct answer is B - the mean extent to which each task was completely and correctly achieved. That's a direct measure of operability.
