Can we consider following instruments for cash component collateral?

#1
Here is the list of symbols ( I am excluding liquidbees/liquidetf and iciciliq from this discussion)
GILT5YBEES
ICICI5GSEC
LICNETFGSC
LTGILTBEES
MOGSEC
SETF10GILT
Are these instruments worth buying for the sake of cash component collateral margin compared to other cash component options available? like Gsec, liquid mutual funds, gilt funds, SGB/ Tbills?
What are average returns of above instruments and what about liquidity ?
