Hi Kunal,
Duplicate data in a drop-down list usually result in errors. You have to create a list for each category and use a unique Define Name. Once you’re done, you can proceed with creating a dependent drop-down list using Data Validation and the INDIRECT function.
Using the data in the sample file you’ve shared, I was able to create a dependent drop-down list. Here’s a link to the edited file stored in OneDrive Online.
Let me know if you need additional assistance.
