A
Both of the solution are Bases
B
Both of the solution are Acids
C
The Baking soda is an acid and the Bleach is a base
D
The baking soda is a base and the Bleach is an Acid.
Explanation: 

Detailed explanation-1: -In a test of pH levels, a baking soda has a pH of 9 and bleach has a pH of 12. What is true about there relationship? The baking soda is a base and the Bleach is an Acid.

Detailed explanation-2: -Baking soda, that is, sodium bicarbonate is a commonly found substance with a pH level of 9. The pH scale ranges from-1 to 15 with lesser number indicating more acidic nature whereas higher number indicating more basicity. Sodium bicarbonate can be said to be basic in nature because of its pH value 9.

Detailed explanation-3: -The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.

Detailed explanation-4: -pH of 9 is ten times more alkaline than pH of 8). pH is a measure of the concentration of hydrogen ions.

Detailed explanation-5: -The range goes from 0-14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
