In your Azure Bot application supporting e-commerce business, you ask users a few questions. Based on the answers to the questions, you provide them with product options and promotions associated with the product. In the first interaction with the user, bot greets the users and asks for his/her name. In the composer “Ask a question” menu, what type of prompt or user input would you use to get the name of the user?

Answer options:

A.Number
B.Text
C.Multi-choice
D.Confirmation

Correct Answer: B
Option A is incorrect because for the number input type is used for numeric values such as user age

In “Bot Asks” tab, input the question along with Welcome Greetings
In the “User Input” tab, enter user.name into the property field, an output format and value.
