Explanation:

✅ C. Messaging for Web and Embedded Service
To allow verified customers to start a chat on the website and continue the conversation during business hours only, the consultant should research Messaging for Web and Embedded Service. Messaging for Web, part of Salesforce Service Cloud, enables customers to initiate chats directly on the website and supports persistent conversations, allowing verified customers to continue their interactions seamlessly across sessions. It also includes authentication capabilities to verify customer identity before initiating chats, ensuring only verified customers can engage. Embedded Service provides the framework to embed the chat experience into the website and configure settings like business hours, restricting chats to specific times. Together, these features meet the client’s requirements for verified customer chats, persistent conversations, and business hours restrictions.

❌ A. Messaging for Web and Einstein Bots
Messaging for Web supports verified customer chats and persistent conversations, but Einstein Bots, while useful for automated responses, are not specifically required for restricting chats to verified customers or enforcing business hours. Einstein Bots focus on automating conversations, which may not align directly with the client’s need for human-agent interactions and business hours restrictions. Embedded Service is a better fit for embedding and controlling the chat experience, making this option incomplete.

❌ B. Web to Chat and Embedded Service
Web to Chat (also known as Live Agent) allows customers to start chats on a website, and Embedded Service can embed this functionality. However, Web to Chat is an older Salesforce feature that does not support persistent conversations as effectively as Messaging for Web. It lacks the robust session management and verification capabilities needed to ensure verified customers can continue conversations seamlessly. Messaging for Web is the more modern and suitable solution for this use case, making this option less effective.
