<u>Answer:</u> The correct answer is Option c.
<u>Explanation:</u>
pH is the measure of acidity of the solution. It is known as power of hydrogen. It is measured in a scale from 0 to 14. The solutions having pH from 0.1 to 6.9 is known as acidic solution, the solution having a pH of 7.1 to 14 is known as basic solution. The solution having pH 7 is known as neutral solution.
Nitric acid is a strong acid because it completely dissociates into its respective ions. The pH of this solution is very low.
Sodium hydroxide (NaOH) is a strong base because it completely dissociates into its respective ions. The pH of this solution is very high.
When a solution of low pH reacts with a solution of high pH, it results in the solution having a neutral pH which is 7.
Hence, the correct answer is option c.
