The correct answer is A. Create a custom Theme in Themes and Branding, selecting logo, brand colors, and images, exactly as stated in the uploaded study guide.

The requirement is to make Lightning Experience conform to the company's existing design guidelines using declarative configuration. The study guide therefore directs the UX Designer to the standard Themes and Branding capability rather than to custom development.

A custom theme allows the organization to apply important brand assets such as the company logo, brand colors, and imagery so that the Salesforce environment presents a recognizable visual identity.

Option B is insufficient because selecting whichever built-in theme happens to be closest does not guarantee compliance with Cloud Kicks' actual design guidelines.

Option C refers to a different branding mechanism and includes font-type configuration, but it is not the declarative approach keyed by the study guide for the current Lightning Experience scenario.

The broader UX principle is to implement branding through supported Salesforce configuration whenever those tools satisfy the requirement. This preserves consistency and avoids unnecessary custom styling while still aligning the environment with company identity.
