Answer:
A
Step-by-step explanation:
I'm assuming you're talking about dry chemicals. An example of where dry chemicals should be stored is yeast, which should be treated in a similar method. In a locked closet, there wouldn't be a lot of external effects and with ventilation, the chemicals would maintain their structure. In a pool closet, obviously, there would be a lot of moisture, so this could cause some explosive reactions to some of the chemicals. The sink in the kitchen has the same properties as in a pool closet. Finally on the ground in the garage wouldn't be a good place to store chemicals as it is cold and has little to no ventilation.
