A. It is a very strong base.

Explanation:

To answer the question we need to ask ourselves several questions

What is pH?

pH refers to the measure of alkalinity or acidity of a substance.

How is pH measured?

pH is measured by determining the concentration of Hydrogen ions (H⁺) in a given solution. Then calculated by getting negative logarithm of hydrogen ions concentration. That is, pH = - log[H⁺]

What does pH tell about a solution?

A solution with a pH below 7 is acidic while a solution with a pH above 7 is basic while that with a pH of 7 is neutral. A pH of 1 to 3 represents a strong acid while a pH of 4 to 6 represents a weak acid. Strong alkali or bases have a pH of 12 to 14 while weak alkali or bases have a pH of 8 to 11. Therefore, a solution with a pH of 14 is a very strong base
