A Correct answer
Explanation

Alkalis have pH above 7 because the pH scale measures acidity/alkalinity, with 7 being neutral. Alkalis are basic substances with pH values greater than 7 (typically 8-14 for common alkalis). Acids have pH below 7, while pH 7 itself is neutral (neither acidic nor alkaline).
