Air is cooled and dehumidified as it flows over the coils of a refrigeration system at 85

Question:

Air is cooled and dehumidified as it flows over the coils of a refrigeration system at 85 kPa from 35oC and a humidity ratio of 0.023 kg/kg dry air to 15oC and a humidity ratio of 0.015 kg/kg dry air. If the mass flow rate of dry air is 0.4 kg/s, the rate of heat removal from the air is
(a) 4kJ/s
(b) 8kJ/s
(c) 12kJ/s
(d) 16kJ/s
(e) 20kJ/s
