(A) Both A and R are correct; R is the correct explanation of A (B) Both A and R are correct; R is not the correct explanation of A (C) A is correct; R is incorrect (D) A is incorrect; R is correct

Tardigrade Admin · Accepted Answer

In biological systems, buffer solution of carbonic acid and sodium bicarbonate is found in our blood. It maintains the

p H

of blood to a constant value of about

7.4

.
Thus,

A

is incorrect but

R

is correct.
