Correct Option: C
for will replace since because –
for (Prep.) is used as—for + Period (duration/of/time)
since (Prep.) is used as — since + point (precise moment in time)
for means from the beginning of the period to the end of the period as in – for 20 minutes
since means from a point in the past until now as in – since morning
Hence, for four hours is the right usage.
