`A overset(lambda_(1)) rarr B overset (lambda_(2))rarr C`
t=0 `N_(0)` 0 0
` t N_(1) N_(2) N_(3)` In the above radioactive decay C is stable nucleus. Then:

A

rate of decay of A will first increase and then decrease

B

Number of nuclei of B will first increase and then decrease

C

if `lambda_(2) gt lambda_(1)` then activity of B will always be higher than activity of A

D

If `lambda_(1) gt gt lambda_(2)` then number of nucleus of C will always be less than number of nucleus of B.
