What is the role of the digital clock during the examination?

The correct choice highlights the primary function of the digital clock during the examination: it indicates the time remaining to complete the examination. This is crucial for candidates, as it allows them to manage their pacing effectively throughout the test. By being aware of the remaining time, examinees can gauge how much time they have left for each section or question, enabling better time management and ensuring they can complete the examination within the allocated period.

The primary focus of a digital clock in this context is to assist candidates in tracking their progress against the total allotted time, which is essential for maintaining an appropriate pace. This feature is especially important in timed exams, where strategic time allocation can influence overall performance.
