Selecting tax slab

Hi All , Just wanted to know which tax slab shall I opt this time in our portal . My ctc is 15.7 (it will increase by this June and cross 16, so I will be coming under 20 % as per the new slab )

I have a loan of 40 lakhs , investment doing 2 lakhs yearly ....

So which option shall I select In portal any suggestions or any more investment suggestions which would save in tax ? Thanks
