    23F* of evaporator temperature is aimed.If there is pressure drop in suction line equivalent to 2F*, and pressure drop in liquid line equivalent to 1F* the selection of compressor should be made for
    a.20 F*
    b.21 F*
    c.22 F*
    d.23 F*

    B. You are correct. If the evap temp needs to be 23 deg and there is an equivilant pressure drop equal to 2 deg from the evap to the compressor than the compressor has to be sized for the suction pressure that it will see not the evap pressure. And that would be the suction pressure equal to the saturation pressure of 23-2 deg, or 21 degrees. Then when you pick the refrigerant you can select the proper compressor for the load.
