Since the notice is regarding non filing of Income Tax Return by your brother, submit a reply stating that he has filed his return for FY 2014-15 and attach a copy of Acknowledgement [ITR-V] as a proof.
If the response is to be submitted online then choose the option return already filed and enter the Acknowledgement Number mentioned in ITR-V.
Since no details have been asked about any of the transactions there is no need for you to raise that issue now.
