Tell me the correct answer with explanation ____________.

• A. A-58 min
• B. B-62 min
• C. C-120 min
• D. D-59 min

Answer 1

The correct option is D D-59 min

It is given that the doubling time of the given bacteria is 1 minute. It means the generation time of given bacterial cells is 60 seconds. If it takes 60 minutes to fill a cup, it will take 59 minutes to fill half the cup.

At 59th minute, the cup will be half-filled and in the 60th minute, the bacterial cell will double up and cup will be full filled.

Thus, the correct answer is '59 min.'
