Solution
The correct option is D 59 minutes
A bacterial cell divides once in every 1 min. It takes 1 hr to fill a cup. The number of bacteria in 1 hour have been formed by half the number of bacteria in the last minute as bacteria cell divides into two in 1 minutes. Therefore half of the cup with bacterial cell would be filled in 59 mins. Hence option B is correct,
