The correct choice is "view_name" because it allows you to create multiple Explores from the same view while ensuring that fields are referenced uniformly across those Explores. In Looker, when you use the view_name in your Explore definitions, you are directly referencing a specific view, allowing for consistent access to the fields defined within that view. This uniformity is crucial for maintaining data integrity and ensuring that all Explores referencing the same view behave consistently in terms of field definitions and calculations.

In LookML, the concept of referencing views through their names facilitates easier management and reduces redundancy. When you need to create multiple Explores that utilize the same set of fields, using the view_name ensures that any changes made to that view will automatically reflect across all Explores that reference it. This promotes better maintainability and reduces the potential for errors that could arise from having duplicated field definitions in multiple views.

The other options, while related to view functionality, do not provide the same level of clarity or uniformity in field referencing as view_name does.
