Explanation:

A Lightning Web Component can contain an Aura component, and an Aura component can contain a Lightning Web Component. This interoperability allows for a smoother transition from Aura to LWC and enables developers to utilize the strengths of both frameworks. However, nesting a Lightning Web Component within an Aura component which in turn contains a Lightning Web Component (Option C) is not a standard practice. For more information, refer to the Salesforce documentation on using Aura and Lightning Web Components together: Salesforce Aura and LWC Interoperability Documentation.
