exempt supply in zero rated supply can avil tax credit?

We can't get refund

As per section 16(3) government has given the benefit in terms of refund to the supplier who supplied zero rated supply.
zero rated suppliers shall we eligible to claim refund either of the following two options:
1st option, submit Bond or letter of undertaking then supply of goods without the payment of integrated tax and claim refund of unutilised input tax credit that it in your case for the cargo ITC.
2nd option, paid integrated tax and claim refund in proportions of total taxable supply within the state and exported.

Thank you
