The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH less than 7 indicates acidity, with lower values being more acidic. Therefore, the order of increasing pH (from more acidic to less acidic or more basic) means moving from a stronger acid to a weaker acid. The correct order, assuming HX, HY, and HZ are all acids, would be from the strongest acid to the weakest acid. Without specific pKa values or acid strength information, we cannot determine the exact order based on the given options alone. However, the question seems to imply a specific order of acidity or basicity among HX, HY, and HZ. The correct answer would be the one that lists the acids from most acidic (lowest pH) to least acidic (highest pH). Given the lack of specific information about the acids' strengths, the answer provided assumes a hypothetical order where HX is the most acidic followed by HZ and then HY as the least acidic, which aligns with option D.
