Answer:

The correct answer is- strong base

Explanation:

A base is said to be a strong base if it completely dissociates when put in an aqueous solution and release OH⁻ ions in the solution. The acidity or basicity of a solution can be checked by checking the pH of that solution.

pH is a scale which have numbers 1-14 that tells about how much acidic or basic a solution is. Solution with pH seven are said neutral and solution with below pH 7 are acidic and solution with above pH 7 are basic.  

A strong base has a pH range between 12 to 14 therefore strong base has very high pH and strong acid have pH 1-3 so strong acid has very low pH. So the correct answer is- strong base.
