Relevant itr form for ay2015-16

I am a resident individual tax payer having income from pension and bank interest only.

In addition, I earned some amount more than Rs. 5000/- during FY 2014-15 from MF redemption invested nearly two years ago.

I want to know the following under the above scenario.

1. What is my appropriate form, ITR1 or ITR2 or ITR2A?

2. Wll  the above mentioned income from MF come under the category 'exempt income for reporting purpose only'

3. What is the last date for filing return for AY 2015-16? Is this date same for all types of form?

Will be obliged for a reply.
