Which ITR for SGB Maturity

Sirs,

We've income from the following sources:

1. Interest (Banks, IT Refund, SGB interest)
2. LIC Pension (Not related to employment)
3. House Rent
4. Dividends from stocks & equity mutual fund
5. SGB Maturity

Usually we file ITR-2, since there typically is capital gain (Stocks & MF). But this year there were no Stock/MF transactions. So only heads of income are as detailed above. 

Is it ok to file ITR-1? 

I ask since SGB Maturity is a capital gain, but exempt, hence I'm wondering if I can show it under Exempt Income -> Any other and get away with just filing ITR-1

Thanks
