How can rate of nuclear decay be equal to rate of formation of radioactive substance?
Why can't option 2 be the answer? Please explain.

it is like, some other nuclei must be decay to form the required nuclei.
suppose we are talking about nuclei name B and it is formed by decay of nuclei A so it can be possible that the formation rate of B = decay rate of B
decay rate is (decay constantno. of nuclei at time t) as No is nuclei no. at t=0 but at any other time it will be different and suppose it is N.
so now rate of decay = rate of formation
