Universal Containers has a Lightning record page that supportsBoth the mobile app and desktop.

The correct answer is C.

The Lightning record page already supports both mobile and desktop, but the downloaded custom component is not visible on mobile. That points to the component itself, not the page activation. Lightning components must be configured to support the required form factors. Salesforce developer documentation explains that components can be configured for desktop form factor Large, phone form factor Small, or both.

So, if the AppExchange component was built only for desktop pages or only supports the large form factor, users cannot view it in the Salesforce mobile app.

A and D are incorrect because the issue is not page activation if the page already supports mobile and desktop. B is incorrect because the scenario states the record page supports both mobile app and desktop.
