Solution

The scientist should use method D: A 100 cm3 measuring cylinder should be used once for each beaker. This is because it allows the scientist to measure and pour 100 cm3 of water in one go, making it the quickest method. The other methods require multiple measurements and pours for each beaker, which would take more time.
