Option B is the way to go. The sum result will show up in the TextView as long as the button click event is properly implemented.

Haha, this code is missing the input method to enter the values of N1 and N2. Option D is the way to go, unless you want to do mental math every time!

I'm not sure, but I think we need to add an input method to enter the values of N1 and N2 numbers.

I think Option C is correct. N1 and N2 need to be converted to Integer first before performing the addition operation.
