D is just misleading; testing can't prove the absence of defects.

Wait, are we really saying exhaustive testing is feasible?

C is definitely the right choice. You can't test everything!

I vaguely recall something about the purpose of testing being to find defects, not just to prove they don't exist, so I'm a bit skeptical about option D.

I think I saw a practice question that mentioned the impossibility of testing all combinations, which makes me lean towards option C as well.

I'm not entirely sure, but I feel like we discussed how automated tests can help, yet they don't completely eliminate the need for manual testing.

I remember studying that exhaustive testing isn't really practical for most software, so I think option C might be the right choice.

I think the answer is C. The idea of exhaustive testing is a common misconception that one of the key principles addresses. Can't test every possible scenario, so you have to be strategic about your testing approach.

Wait, I'm a little confused. Are we supposed to be talking about automated testing vs. manual testing? Or is this about the purpose of testing? I want to make sure I understand the question properly.

Okay, I've got this. The key principle here is that exhaustive testing is not feasible, so the correct answer is C. Gotta remember that for the exam.

Hmm, I'm not sure about this one. The principles of software testing can be tricky. I'll have to think it through carefully before answering.

This question seems pretty straightforward. I think the answer is C - it's normally impossible to test all input/output combinations for a software system.

Option A sounds tempting, but I think C is the way to go. Automated tests are great, but they can't catch everything. Manual testing is still essential.

Haha, Option B is a joke! Exhaustive testing is like trying to find a needle in a haystack the size of the Eiffel Tower. Good luck with that!

I'm going with Option D. The purpose of testing is to demonstrate the absence of defects, not to find them. Clearly, the best software is one with zero defects, right?

Option C is the best answer. It's simply not possible to test every possible input and output combination for a software system. That's just basic software testing knowledge.
