Hello aspirant,

It is advised that you upload a valid photo ID issued by the government, one that is authorized by someone in power. such as Aadhar card, PAN card, driving license, etc. In case you choose to upload your college ID as photo ID proof, you can mention your autonomy roll number as the ID number. Don't mention the class roll, because it keeps varying from stream to stream.

Hope this helps you. Feel free to revert back in the comments.
