Final answer:
The correct answer is c. ABC Accountants' approach of tailoring services to individual client needs is an example of custom production, which is highly personalized and differs significantly from standardized mass production techniques.
Step-by-step explanation:
The ABC Accountants do not standardize their service to customers because each customer has different needs. This is an example of custom production, which is option c. Custom production, also known as customized production, refers to the creation of products or services that are tailored to the specific requirements of individual customers. Unlike mass production where the focus is on producing large volumes of standardized items, custom production involves making items to order, which can range from bespoke suits to personalized accounting services as in the case of ABC Accountants.
Each client may require a unique set of services based on their financial situation, making the service inherently variable. For instance, one client may need tax preparation while another might need in-depth financial analysis or auditing. ABC Accountants uses a personalized approach to address these various demands, thereby demonstrating custom production characteristics.
