There is always option B xD

A scientist has a special bacteria that when he places a batch in a beaker, can double in volume every minute. He puts a few of the bacteria in a beaker. In an hour, the beaker is full. When was it 1/4 full?

Working backwards, it must have been 1/2 full at 59 minutes, because in the 60th minute it doubled in volume. Similarly, it must have been 1/4 full at 58 minutes.
