Does interest on fixed deposits taxable for trust entity ?

My client is a Charitable Trust registred u/s 12AA. 

I am filling ITR-7 for it. There is only two incomes- 1) Voluntory Donations and 2) Interest on Fixed Deposits. 

I have filled details of Voluntory Donations in schedule-VC of ITR-7 and details of Interest on FD in schedule- OS. 

And details of expenses incured in the schedule-ER. Is it right or i should entered this details in any other schedule ?

Does Interest on Fixed Deposits is exempt for trust ? And where it should be shown in ITR-7 ?
