3.

Which statement is the best definition of intent in the context of a virtual assistant?

Intent is the classification of the inputted question Intent is the specific class of object that is relevant to a user' s purpose Intent is used to figure out if other IBM Watson AI services are required Intent is the answer to the inputted question

4.
