Few drops of aqueous solution of ammonium chloride are put on a universal indicator paper. The paper turns pink. Study the following table and choose the correct option.
Nature Ammonium chloride is a salt of .... Range of pH
(a) acidic weak acid and strong base less than $\displaystyle 7$
(b) basic weak acid and strong base more than $\displaystyle 7$
(c) acidic strong acid and weak base less than $\displaystyle 7$
(d) basic strong acid and strong base $\displaystyle 7$

The official answer to this question is still being verified, so it is not published yet.
