Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
$p H$ of Blood should not change even slightly as it results in condition called acidosis which is serious and also many chemical reactions of proteins are dependent on $p H .$
So blood is a buffer mixture of Carbonic acid and bicarbonate which does not allow the $p H$ of blood to change even with intake of acidic foods.
The reason is the correct explanation for the assertion.
