I'll go with C. Checking call correctness is more about interface testing than decision coverage.

Haha, D is definitely the wrong answer. Decision coverage is all about 100% coverage, not just half-baked testing!

A and B seem like the most relevant options for decision coverage. I'm leaning towards D being the correct answer.

I'm not sure about D. Decision coverage is usually about ensuring 100% coverage, not just 50%.

Option C seems like the odd one out. Deciding which program modules to call is more about integration testing, not decision coverage.
