Already Paid but got the same amount of demand notice

1. Amount already paid. (attach challan details).

2. Interest is calculated after the payment of existing demand, so it is required to be paid.

Both are welcome for quick response. Now after clicking the submit response button there is two option 1) Demand is correct and the second one is "Disagree with demand" , I must choose second one. Then I opted to give reason from 1 to 8 reason. Now I thing I must go with any of first two. Here are the first two options

1. Demand paid and Challan has CIN (Without open challan details)

2. Demand paid and Challan has CIN (With open challan details)

I have paid the amount and have  receipt with challan number and all the details. Which one I choose. Not understood. Pl give advice. 

Thanks for the response.
