The choice highlighting that queries should select the fewest fields to avoid exceeding governor limits is correct because Salesforce enforces strict limits on resources, including the number of records retrieved and the amount of data processed in a single transaction. When writing Apex code, selecting only the fields that are needed for processing optimizes the query and reduces the overall footprint of the operation. This practice helps maintain efficiency, preventing governor limits from being hit, which can lead to exceptions and failures in the execution of the code.

By selecting minimal fields, developers can also reduce the amount of data that needs to be serialized and sent over the network, which enhances performance and responsiveness in a multi-tenant environment where many customers share the same resources. Overall, this approach is aligned with best practices for efficient and scalable coding in Apex, particularly on the multi-tenant Salesforce platform.
