In your chat application, you decide to use multimedia attachments to enhance user interaction. In the first interaction with the user, your bot uses a basic card with a single large image, one button and a few lines of plain text. The image displays a product or category, the button offers a link to your website, and the text displays the title text for the product or category. In the second interaction, your bot uses a combination of text, speech, images and input fields. It renders a JSON object response into your chat application for an engaging experience. 
Given the scenario above, which card would you choose to add to your bot for the first (Interaction1) and second Interaction (interaction2)?

Answer options:

A.Interaction1 -> Hero Card; Interaction2 -> Adaptive Card
B.Interaction1-> Thumbnail Card; Interaction2 -> Adaptive Card
C.Interaction1 -> Adaptive Card; Interaction2-> Thumbnail Card
D.Interaction1 -> Adaptive Card; Interaction2 -> Hero Card

Correct Answer: A
Option A is correct because a large image, a button, and some text are displayed through the multimedia attachment in the first interaction. The Hero card is suited for that purpose. A JSON object provides a flexible and rich experience to the user through an Adaptive card in the second interaction.
Option B is incorrect because the image used in the first interaction is large. However, the Thumbnail card uses a thumbnail image.
Option C is incorrect because Interaction 1 is suited to use the Hero Card, and Interaction 2 is suited to use an Adaptive card.
Option D is incorrect because Interaction 1 is suited to use the Hero Card, and Interaction 2 is suited to use an Adaptive card.
