The correct answer is C. Component Blueprints, as identified by the uploaded study guide.
The question emphasizes consistency with the look and feel of Lightning Experience across components that will appear repeatedly on different pages. The study guide therefore points to SLDS Component Blueprints as the relevant resource.
A Component Blueprint provides the documented structure and styling pattern for implementing an interface component according to SLDS conventions. Using a standard blueprint helps prevent different developers or teams from creating visually inconsistent versions of the same interaction.
Option A, Experience Lightning Components, is not the SLDS resource identified by the guide for this purpose.
Option B, Lightning Component Builder, is likewise not the design-system resource referenced in the answer key.
The important distinction is between a design-system specification and an application-building tool. A blueprint establishes how a component should be structured and presented so that custom implementations remain aligned with Salesforce's established design language.
When components are reused on many pages, that consistency becomes especially important because variations in spacing, states, structure, or interaction patterns can create an uneven user experience.
