Problem

In the following chain,

A\to B\to C

A

and

B

are radioactive, while

C

is stable. Initially, only

A

and

B

nuclei are present; there are no

C

nuclei. As time passes, match the two columns.

Column I	Column II
(a) Nuclei of $(A+B)$	(p) Will increase continuously
(b) Nuclei of $B$	(q) Will decrease continuously
(c) Nuclei of $(C+B)$	(r) Will first increase, then decrease
(d) Nuclei of $(A+C)$	(s) Data insufficient
