Param,
If you have paid full year fee and purchased GIC, then you need not show any other income or funds proof at all. Please check the checklist at CHC VFS link. It's also advisable not to provide documents which are not asked for. CHC is not asking for proof of funds under SPP. Hence, just a few documents. Go through the checklist. That option is for general category, they need to show funds, proof of funds, bank statements and so on....
cheers!
