Answer and explanation

Correct answer

A. Create indexes to support the dominant filters and lookups instead of adding them blindly.

Why

Create indexes to support the dominant filters and lookups instead of adding them blindly. That is the stronger engineering move because interviewers often use index questions to test whether you connect database design to real access patterns. Random indexing can add write cost without helping the queries that matter.
