A is an aqueous solution of acid and b is an aqueous solution of base. these are diluted separately. then
a. pH of a increases while that of b decreases till neutral
b.pH of b decreases while that of a increases till neutral.
c. pH of a and b decreases
d.pH of a and b increases
also state the reason for your choice

Option a is correct.
A is an acid whose pH is always less than 7. When you dilute the acid, the pH value increases till neutral condition i.e., pH 7 is reached.
B is a base whose pH is always more than 7. When you dilute the base, the pH value decreases till neutral condition i.e., pH 7 is reached.
