Which of the following is NOT listed as an essential service?

The option indicating dry cleaning services is the correct choice as it is not considered an essential service. Essential services typically encompass those amenities and utilities necessary for a household to function safely and healthily. They generally include hot and cold running water, gas for heating and cooking, and in some contexts, the availability of appliances like refrigerators, which are crucial for food preservation and safety.

Dry cleaning services, on the other hand, are not vital for basic living needs. They are an added convenience that many people may use for maintaining their clothing, but they do not affect the day-to-day health and safety of tenants in the way that essential services do. Thus, when evaluating what constitutes an essential service, dry cleaning is categorized as a non-essential luxury.
