The correct answer is C. Compact layout.

Compact layouts control the key fields shown in the record highlights area at the top of a record, including in the Salesforce mobile app. Salesforce documentation states that compact layout fields populate the record highlights section at the top of record views in the Salesforce mobile app.

A. Mobile navigation controls navigation menu items, not fields on a record.

B. Record Detail component shows record fields but does not specifically place key fields at the top.

D. Object specific action is used for actions, not at-a-glance field display.
