I have an OS partition (C) and a Data partition (D) with non-OS files. If I choose any of the three options, will this only affect the C: partition or will it reformat the entire physical drive, thus also removing the D partition?

Okay I took a plunge in the deep and selected "Nothing.", the harshest option. I assume the other two will behave the same way.
After the installation my partition was still there. So when upgrading, all three options will only affect the partition that has Windows already installed.
It is possible the drive letter will have changed because there might be other media attached (e.g. a USB stick). This can easily be fixed by unplugging said media and changing the drive letter in Disk Management (right-click the Start button).
I suggest caution if you have a multiple OS'es though.

Yes; It does. If you have any doubts you should backup your data. – Ramhound – 2015-08-05T17:14:30.857
Source? Because it doesn't... – Jan M. – 2015-08-05T17:50:48.123
1To understand my original comment. I read "If I choose any of the three options, will this only affect the C: partition" and replied with the following statement. Yes; It does. I went on to indicate if you had any doubts you should back up your data. I never attempted to indicate anything else. – Ramhound – 2015-08-05T18:26:12.667
Oh ok. I considered the second part ("... or will it reformat...") too and then a "Yes; it does." was a bit vague IMO, especially when getting it wrong would have serious consequences. – Jan M. – 2015-08-05T20:50:22.037
