Final answer:
The term 'Billing Cycle' represents the period for tracking and billing customers for cable services. It is a recurring time frame, often monthly, in which services are charged and bills are generated for customers. The correct option is A.
Step-by-step explanation:
The period for tracking and billing customers for cable services is known as a Billing Cycle. This term is synonymous with the time frame during which charges for services are incurred and later billed to the customer.
The billing cycle, which can differ among providers and service plans, is usually reflected in monthly statements sent to customers detailing the charges for that specific period.
The Service Period, Subscription Term, and Account Duration may relate to the overall length of service or contractual obligations, but the Billing Cycle specifically refers to the recurring period for billing purposes, often quoted in months.
