Congrats @ Muralidoss.
In above question how the tax liability is discharged is not mention .i.e (cash or credit ledger utilization)
Refund is only possible where there is actual payment .If the tax liability is disposed off by utilizing the credit Ledger, refund is not entertained.(You may also go through the online refund application format).Hence in above question, if the 3b liability is discharged through making payment by cash ,only then the refund application is possible.
In this case you have to select 8th in the sequence of refund types mentioned there in.
