What are conversational agents primarily used for?

Conversational agents are primarily designed to automate interactions by facilitating natural language dialogue between users and machines. This technology leverages natural language processing (NLP) to understand user input and generate human-like responses, allowing for efficient communication in a variety of applications, such as customer support, virtual assistants, and chatbots.

The focus of these agents is on enabling practical and effective verbal or text-based communication, making option A the most appropriate choice for their primary use.
