Final answer:
The correct answer is option c.In the given scenario, the entry of the customer's details by the shop owner is best defined as a 'Task in Process', which is a step in the larger ordering process.
Step-by-step explanation:
The entry of a customer's name, address, and contact number in the scenario where a shop owner is taking a telephone order for a new vacuum cleaner represents "c. Task in Process". In a business context, a process refers to a series of tasks or activities that are carried out in order to achieve a particular outcome or goal.
Taking and confirming customer details is one of the individual tasks within the larger process of completing a sale or order. It is a discrete step necessary to move the process forward.
The process itself would encompass many tasks, such as selecting the product, recording customer information, processing payment, arranging delivery, and providing post-sale support. Hence, option C is the best representation of this activity.
