You create a chatbot that provides local information. Users can get information about the local weather, working hours of the shops, current movies playing in local theaters, and others. At the beginning of a conversation, the bot asks users to input their city name or a zip code. 
What type of the variable does chatbot use to store this information?

Answer options:

A.Global
B.Topic
C.Local
D.Bot
E.Public

Correct Answer: D 
During conversations, Power Virtual Agents chatbots collect user`s information and store it in the variables. The variables help chatbots to keep an intelligent conversation by avoiding asking to provide the same information several times. The variables also serve as parameters and outputs in the chatbot`s integration with Power Automate and Power Apps. 
The chatbot’s variables have their scope. There are two types of 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 topic where they are created. 
When the bot asks users to provide information about their city or a zip code, this information is stored in a variable with the "global" scope — bot variable. Because if the bot stores this information in a variable with the topic`s scope, it must ask users to supply their city or zip code once more when they change the topic from the local weather to the movies. 
All other options are incorrect.
