68/73 are the two standard sizes of the BB threads. You will need to find out which one it is.

110mm is the width of the axle so you can fit whatever one matches your chainset.

68mm and 73 mm are both standard bottom bracket shell widths. most bikes tend to have 68mm.

i thik the fact that it lists both on your BB indicates that it can be fitted to either sized shell.

the 110 does represent the width of your axle.

one thing you havent mentioned is what type of axle you need to match your chainset, is it :
square taper (4 sided)
octalink (8 splines)
power spline (10 splines)

If it is square taper, try this

supersonic

Or ISIS.

Some BBs come with spacers to allow them to be fitted to 68 or 73mm shells.

it is an isis drive, it will accept either 68/73

it is 110mm but i can ifnd one this width but i can a 113mm
so what will happen if i fit the 113mm

supersonic

It will push the chainset outboard, altering chainline.

It should work, you will just need to readjust the front mech' as the chain rings will have moved outwards by 1.5mm.
