During biology lab, Stacey needs to pour 100 mL of a substance into a beaker. She inspects the beaker before she uses it and sees that there is a small crack in the bottom of the beaker. In order to practice proper laboratory safety, Stacey should A. inform her teacher and use a different beaker. B. fill the beaker with water and only use the beaker if it doesn't leak. C. put tape over the crack but go ahead and use the beaker. D. switch beakers with another student in the lab.

According to the safety standards specified to perform experiments in a laboratory, Stacey should inform her teacher and try to use a different beaker if she sees a crack on hers.

This is to ensure maximum safety which in no case should be compromised. Because the beaker still might break in the middle of an experiment, even if it was not leaking before or she covered it with a tape, thus causing harm to her.
