Solution

The correct option is B Both Assertion and Reason are correct and Reason is the correct explanation of Assertion
Blood contains a mixture of $H_{2} C O_{3}$ and $H C O_{3}^{-}$ which acts as acidic buffer solution.
Thus blood has the tendency to resist changes in pH when small quantities of acid or base are added.
