D is partially correct. Agricultural products are mainly stored in a temperature controlled environment. Meanwhile medical product do need to be stored in a climate controlled environment.

This can never and should not be B. The right answer is D. I hope this answers can be reviewed on a weekly or daily basis please to reflect the right answers.

Answer is D First, strike a balance between temperature and humidity While temperature controlled utilities control only the indoor temperature, climate-controlled warehouses control both temperature and humidity. It is critical that both of these climatic conditions are optimized at a relative measure to keep inventory in good condition. Whether it is the scorching heat of the Western states or the biting cold of Alaska, the indoor temperature and humidity of the warehouse must be maintained at optimum levels. Why? When outdoor temperature levels increase, so does humidity and vice-versa, which might be unfavorable for many products, especially agricultural produce and perishable goods. Too much humidity can spoil temperature-sensitive goods like medicines which require cold storage conditions, often in sub-zero temperature without humidity. Climate-controlled warehouses come with dehumidifiers that maintain temperature and humidity levels at optimum levels. Dehumidifiers also help you keep mold, dust mites, mildew, etc. from growing on your goods.
