Start at the layer that controls the outcome. The best answer is C. Set up a delegated approver for the manager. The selected option is not chosen because it sounds familiar; it is chosen because it gives Salesforce the right instruction at runtime. Lightning App Builder controls page composition, component visibility, activation, assignments, and specialized surfaces such as record pages, home pages, and utility bars.
The scenario describes a business outcome, not merely an administrative preference. If the feature is configured correctly, users get the intended result without depending on memory, spreadsheets, or manual policing. That is the professional standard for Platform App Builder work: place the rule in metadata, test it under the correct permissions, and keep the design supportable.
The distractors are not equal substitutes. A (Have the manager ' s assistant reassign the approval request.) handles a different concern; An approval process is for formal sign-off, not for every automation, display, import, or security requirement. B (Use a quick action to forward the approval request to the next level approver.) is less defensible because An approval process is for formal sign-off, not for every automation, display, import, or security requirement. D (Use an assignment rule to automatically assign a delegated approver.) would be fragile here because it could produce an inconsistent result once different users, records, or apps are tested. That is the kind of solution a Salesforce admin can document, migrate, and troubleshoot without creating hidden technical debt.
