Hello! This part is called a channel balance. Yours in particular appears to be a match for our S795-26 .

Just note that our balance screws to the top of the window track, while yours installs with a hook. You can still use ours but you will also need to purchase our 26-200 separately. This pops into that square hole and remains in place, allowing you to screw our balance in.

What do these different options mean?

Those represent the calibration of the spring. You can see a chart just under the product description that explains exactly how much weigh each option supports.

According to your initial post, you need the 27C stamp.
