In a solution, a buffer is a substance that releases and catches Hydrogen ions keeping the same pH. A buffer is resistible on pH change by taking Hydrogen ions whenever acids are being added to a solution. Whenever bases are added, it donates hydrogen ions. Therefore, the answer to this question is letter A.
