A Correct answer
Explanation

This is a demo/test question with placeholder content. Option A is marked as correct, but all options are generic placeholders ('Demo 1', 'Demo 2', etc.). The question content 'Demo 1' doesn't test any actual knowledge. This appears to be a malformed entry used for testing the quiz system rather than a real question.
