Laundry taps location and type

About to renovate this laundry and add cabinets and built in trough/sink:

Will need a plumber to move taps, as new position will be under the window.

My question: which option will be cheapest and easiest for the plumber:
a) Move taps under the window coming out from the wall (same style as in picture)
b) Move taps under the window but at a height under the benchtop and connect them to mixer in the sink via flexible hoses
c) Move taps to under the cabinets in their current position and run flexible connectors across under the bench to the sink (is this possible?)

Thanks for your help
