 To wrap a Lightning Web Component inside an Aura component, you need to use the  tag, where c is the default namespace for custom components. This tag allows you to reference the Lightning Web Component by its name and use it as a child component of the Aura component. You also need to use the lwc:dom="manual" directive on the Aura component to indicate that you are manually rendering the Lightning Web Component inside the Aura component. This directive prevents the Aura component from interfering with the rendering of the Lightning Web Component. Option C shows the correct syntax for wrapping a Lightning Web Component inside an Aura component. Option A is incorrect because it uses the  tag, which is not a valid tag for referencing a Lightning Web Component. Option B is incorrect because it uses the  tag, which is also not a valid tag for referencing a Lightning Web Component. Option D is incorrectbecause it does not use the lwc:dom="manual" directive on the Aura component, which is required for manually rendering a Lightning Web Component inside an Aura component. References: Composition | Lightning Web Components Developer Guide, Using Lightning Web Components inside Aura Components, Aura Coexistence | Lightning Web Components Developer Guide

For maintainable and scalable Lightning Web Component development, it's recommended to style components by targeting the :host pseudo-element in the component's CSS file and by applying Salesforce Lightning Design System (SLDS) classes to internal elements. These practices ensure consistent styling that aligns with Salesforce's design standards and provides a clear separation of concerns between component structure and styling.

To make Lightning Web Components mobile-ready, one maintainable approach is to create a Lightning app page and then add the component to the mobile navigation. This ensures that the component is accessible and optimized for mobile users within the Salesforce mobile app. Another approach is to design the component's templates with responsiveness in mind, using CSS and layout techniques that adapt to different screen sizes. Salesforce documentation on mobile-ready development practices provides guidelines on creating responsive designs and optimizing components for mobile use.

The sfdx commerce:store:quickstart:setup command allows the developer to set up a store from scratch using a definition file that specifies the store configuration. This command performs the following tasks:

• Pushes the store sources to the scratch org
• Creates a buyer user
• Imports products
• Creates a search index
• Opens the store in a browser

The other options are not correct because:

• A. sfdx commerce:store:quickstart:create only creates a community for the store, but does not perform the other tasks required to set up a store from scratch.
• C. sfdx commerce:store:create creates and sets up a store, but does not use a definition file to specify the store configuration. Instead, it uses command-line flags to provide the store parameters.
• D. sfdx commerce:store:open only opens an existing store in a browser, but does not create or set up a store from scratch.
