Solution

The correct option is A acidic buffer
A buffer solution is one which resists changes in pH when small quantities of an acid or an alkali are added to it.
An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt.
