Answer :
The correct option is B) Inseparability. Personal trainers rely on the inseparability feature of services, which refers to the simultaneous production and consumption of a service, necessitating the presence of the client.
Personal trainers cannot complete their work without their clients present because of the inseparability feature of services. This characteristic indicates that services are often produced and consumed simultaneously and cannot be separated from the service providers.
A personal trainer's services are delivered when the client is present to receive them, illustrating the inseparability between the service's production and its consumption.
