You publish your bot and add it to Microsoft Teams for personal use. But you need to share the bot with your organization. 
What are two options you can use to achieve your goal?

Answer options:

A.Import bot to Teams
B.Download a manifest file
C.Select your bot from the Teams app store
D.Submit for admin approval

Correct Answers: B and D 
After you publish your bot and connect it to the Microsoft Teams channel, you can share the link to your bot with people in your organization. But if you want that anybody in your organization finds your bot and installs it for their use, you need to share the bot with your organization. After you share your bot with your organization, the bot will be placed in the Teams Apps Store under the “Built by your org” section. 
There are two ways to do that: to submit the bot for admin approval and download the bot’s manifest file. 
To access both options, you need in the Power Virtual Agents portal under the Manage section to open the Channels (Number 1). Then select the Microsoft Teams option (Number 2). If your bot is already connected to the Teams, you will see the information about your boat (Number 3) and the “Share with my organization” section, and the “Submit for admin approval” button (Number 4). 

After you push the “Submit for admin approval” button, on the next screen, you will see two buttons, the “Submit for admin approval” (Number 1) and “Download manifest” (Number 2). 
Also, there is an App ID (Number 3) that you can copy and use for Teams configuration of Single Sign On (SSO) if you use a manual authentication with Azure AD. 

After you review the requirements above the button and confirm that everything is correct, you can click on the “Submit for admin approval” button and finally confirm the submission. The request is sent to the admin for approval. You should wait till the status of your request will be updated to Approved. And then, you can find your bot in the "Built by org" section. 
If you download a .zip manifest file by clicking the “Download manifest” button, you can give it to the admin for an installation as an organization-wide bot. You can also upload a manifest to the Microsoft Teams as a custom app if your Teams organization’s policy allows uploading custom applications. 
All other options are incorrect.
