Final answer:
In the event of a bromine spill, one should evacuate the area immediately and use a chemical neutralizer to absorb the bromine, while also ensuring to ventilate the room to disperse the toxic fumes.
Step-by-step explanation:
If a few drops of bromine are spilled onto a benchtop, the correct course of action is to first evacuate the area immediately. Bromine fumes are toxic and can pose a health hazard. Secondly, you should use a chemical neutralizer to absorb the spilled bromine. It's important to be trained on the proper neutralizer to use and to follow safety protocols rigorously. You should also ventilate the area to disperse the bromine fumes, as working in a well-ventilated room is crucial when handling chemicals. However, the first response should be to follow instructions number 4 mentioned in your reference, which is to call your teacher at once in the case of a chemical spill.
Therefore, the most comprehensive and correct answer to the question is d) Both a and b - Evacuate the area immediately and Use a chemical neutralizer to absorb the spilled bromine.
