Which of the following is an example of large scale computer applications in business?

Insurance claims processing systems are a prime example of large-scale computer applications in business due to their complexity and the volume of data they handle. These systems are designed to manage and streamline the entire insurance claim process, from the initial submission through to resolution. They involve various functions such as data entry, verification, assessment of claim validity, and payment processing.

These systems integrate with various databases and technologies to ensure that all claims are processed efficiently and in compliance with regulatory standards. Given that insurance companies deal with a vast number of claims daily, the ability to automate and manage these processes effectively is crucial for operational efficiency and customer satisfaction.

In contrast, while public record systems, diagnostic tools in healthcare, and vehicle registration systems are certainly significant applications, they may not encompass the same breadth and complexity of operations as insurance claims processing systems. They may focus on narrower functions or operate within more limited data parameters compared to the extensive nature of claims processing in the insurance industry.
