You have a chatbot application in Azure and you want to prompt the user for an input in a long conversation. The user provides the input in a boolean value. The bot validates the input value and continues the conversation or provides the information from the knowledge base. Given the input value is boolean, which dialog prompt type would you choose. (select one answer choice)

Answer options:

A.Text prompt
B.Choice prompt
C.Number prompt
D.Confirm prompt

Correct Answer: D
Option A is incorrect because the Text prompt requires an input string in the form of text.
Option B is incorrect because the Choice prompt requires a set of choices to select from.
Option C is incorrect because the Number prompt requires a numeric value and hence a number is required input for this prompt.
Option D is correct because the Confirm prompt asks for a confirmation and hence boolean input is required for this prompt.
