Based on Karnataka’s OBC list and APDSC (Andhra Pradesh DSC) norms , here’s a structured approach:

• APDSC follows Andhra Pradesh’s OBC list , not Karnataka’s.

• If applying in Karnataka : Use Karnataka’s OBC certificate (e.g., Category 2A, 3A)

• For Karnataka-Based Applications
  If you’re applying in Karnataka (assuming a typo in "APDSC"):

  • OBC Sub-Castes :

    • Category 2A : Balija, Bestha, Gangaputra

      Recommended

    • Category 3A : Uppara, Vishwakarma.

    • Full List : Refer to the Karnataka OBC PDF ( Result 1 (https://www.ncbc.nic.in/Writereaddata/cl/karnataka.pdf) ) for your exact sub-caste.

  • OC Option :

    • Avoid OC if you hold a valid Karnataka OBC certificate, as it reduces competition (OBC has reserved seats).

    • If opting for OC : You cannot claim reservation benefits .

• Do Not Opt for OC : As an OBC candidate, selecting OC forfeits your reservation eligibility , increasing competition.

• Verify Sub-Caste : Cross-check your caste in Karnataka’s OBC list ( Result 1 (https://www.ncbc.nic.in/Writereaddata/cl/karnataka.pdf) ) and match it exactly in the application.
• Example : If your caste is Balija (2A in Karnataka), select "Balija" under OBC. Do not choose OC .

  Final Answer : Do not select OC . Choose your exact OBC sub-caste from Karnataka’s OBC list (e.g., Balija, Uppara) to retain reservation benefits. If applying in Andhra, confirm eligibility first.

As you can see choose whether to take it or not its upto you but you can opt for OBC  its the better option.However you can match your resuts from the above links provided and search further for it .always takes what's suitable for future refrences.

Hope it will help you clear your mind.
