The correct Answer is:
A
Suppose 10000 bacteria is required to fill the cup and it takes 1 hour (60 min) to form 10000 bacteria. Then half the cup is 5000 bacteria and that is just before the final division which is it takes 59 minutes to fill half the cup and 60 min to fill the cup as the growth is exponential.
