Answer»

The CORRECT choice is (c) It means that the structure should perform satisfactorily under different loads, without discomfort to user

For explanation I would say: SERVICEABILITY is related to utility of structure. The structure should perform satisfactorily under SERVICE loads, without discomfort to user due to excessive DEFLECTION, cracking, vibration, etc. Other considerations of serviceability are durability, impermeability, acoustic and thermal insulation etc.
