The primary purpose of a vernier caliper encompasses multiple measurement functions, and it excels in improving accuracy in measurements as well. A vernier caliper is a precision tool that can measure external dimensions (such as the thickness or width of an object), internal dimensions (like the diameter of a hole), and depths (for example, the depth of a hole).

The design of the vernier caliper allows it to have a main scale and a sliding vernier scale, which provides the ability to take very fine measurements that are more precise than many other measuring tools. This level of precision is essential in industrial settings where accuracy is critical for part fabrication and assembly.

Its ability to perform a variety of measurements efficiently contributes to its comprehensive utility, making it a valuable instrument for technicians and engineers. Thus, the correct answer reflects the multifaceted role that a vernier caliper plays in measurement tasks.
