In terms of immigration, which of the following best defines "inspection"?

The best definition of "inspection" in the context of immigration is a formal process to assess lawful entry. Inspection refers to the comprehensive examination conducted by immigration officials to determine an individual's eligibility to enter a country. This process often includes verifying the traveler's documentation, checking for any legal grounds that would prevent entry, and ensuring that the traveler complies with immigration laws.

This assessment is crucial for maintaining a country's borders and ensuring that those entering abide by its laws and regulations. It goes beyond merely looking at a passport or casually reviewing identification; it involves a thorough evaluation of various factors relating to the traveler's background, purpose of travel, and potential risks.

While the other choices touch on aspects of the inspection process, they do not encapsulate the full scope and importance of what inspection entails in immigration terms. A legal evaluation, for instance, might be part of the inspection but does not fully capture the formal and comprehensive nature of the process. Similarly, a casual review or a detailed examination of personal belongings involves only specific components of the broader inspection procedure. Thus, understanding inspection as a formal process to assess lawful entry accurately reflects its significance in immigration contexts.
