A sample of a radioactive nucleus A disintegrates to another radioactive nucleus B , which in turn disintegrates to some other stable nucleus C . Plot of a graph showing the variation of number of atoms of nucleus B vesus time is : (Assume that at t = 0 , there are no B atoms in the sample)

Correct answer

2
