The problem is that it you are attempting to measure two different things with the same question: depth of knowledge and frequency of usage. It's possible that someone knows C quite well, but no longer (or never) uses it.
It's similar to offering 3 options for Marital Status: Single, Married or Divorced. It's impossible to interpret the results in any meaningful way (Divorced and single? Divorced and remarried? Is it important that I've ever been divorced? Or do you just want to know if I'm currently married or not?). It's better to separate these questions.

What if I added a phrase to option two: "Or I learned C extensively at one point, remember most of it, but don't use it regularly anymore" and to option three: "Or I learned C extensively at one point, but have forgotten most of it and don't use it anymore?"
- qjz 16y agoSorry, I should have added that it seems obvious the emphasis is on depth of knowledge and the frequency of usage parts are merely there as helpful tips. I personally hate modifying a survey once it's been deployed and suggest you leave it as is.
