@Ghulam Sarwar welcome to the Atlassian community 

Each one is a product instance.  You currently have two Jira sites and o e Confluence space.  It is asking you to choose the product instance you have a question about.  You should be able to identify the product by its url.

Hi @Ghulam Sarwar , You have two Jira product under different sites and one confluence. In Atlassian cloud, The hierarchy is like, You will have ORG at the top, then comes sites and underneath a site you can enable one product of each type.

In your case you have two sites and Jira product in both the sites.

I am not sure if this what you intended to ask, please let me know if your ask is something else. Thanks

@Ghulam Sarwar - the other posts have nailed it.

The top Jira - this is a Jira instance available at https://brandcrock.atlassian.net

The middle Confluence - This is a Confluence instance available at https://brandcrock-team.atlassian.net

The bottom Jira - Another instance of Jira at https://brandcrock-team.atlassian.net.

All 3 are "cloud" versions of that software.  The bottom two will be available from the same URL, the top one will not be as it has a different URL.

Hope this all helps and please drop any followup questions!
