Solution

The correct option is A Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1.
According to pH scale, acidic have pH range from 1 to 7 while bases have pH range from 7 to 14.
addition of acids to neutral solution at pH 7 generally lowers the pH value.
If acid is added, $[H^{+}]$ concentration increases. So, $p H$ decreases slightly.
