Answer:
Option A. neutral
Explanation:
we know that
The pH is a number that describe the concentration of hydrogen ions in the solution. A solution's pH will be a number between 0 and 14.
A solution with a pH of 7 is classified as neutral. 
If the pH is lower than 7, the solution is acidic. 
If the pH is higher than 7, the solution is basic. 
In this problem we have a solution that has a pH=7
therefore
The solution is classified as neutral
