Solution

The correct option is A Sodium bicarbonate > water > lemon juice
The highest pH values are shown by bases while the acids give low values on pH scale.Sodium bicarbonate is a strong base with pH value greater than 7, water is neutral with pH 7 while acids like lemon juice have pH value less than 7 on a pH scale of 14. So, the decreasing pH order is (sodium bicarbonate > water > lemon juice).
