Correct Answer: B
The variables help chatbots to keep an intelligent conversation by avoiding asking to provide the same information several times.
There are two types of chatbot’s variables: Topic — variables with a limited scope that can be used within a topic.
Bot — variables with “global” access from any topic across the entire bot during a single user session.
By default, the variables have a scope of the topic where they are created. The variables also serve as parameters and outputs in the chatbot`s integration with Power Automate and Power Apps.
At the beginning of a conversation, the RentMe bot should ask users to select their location from three options. Then the bot will use the location for several topics, like directions or car inventory. Therefore, a bot should store the selected location in a variable with a “global” scope for the bot — a Bot variable.
All other options are incorrect.
