    Answer : Option A

    Explanation :

    Sensible Heat Ratio - SHR - is defined as the sensible heat or cooling load divided by the total heat or cooling load.
    SHR = qs / qt = qs / (qs + ql)
    where SHR = sensible heat ratio (ratio of sensible heat load to total heat load) qs = sensible heat load (kW, Btu/hr) qt = total heat load - sensible heat and latent heat (kW, Btu/hr) ql = latent heat load (kW, Btu/hr)
