Universal Containers (UC) needs to wrap a Lightning Web Component they have created called "lwcContainerComponent”...

 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 incorrectbecause it uses the  tag, which is also not a valid tag for referencing a Lightning Web Component. Option D is incorrect because 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
