An equimolar mixture of carbon dioxide and water vapor at 1 atm and 60oC enter a dehumidifying

Question:

An equimolar mixture of carbon dioxide and water vapor at 1 atm and 60oC enter a dehumidifying section where the entire water vapor is condensed and removed from the mixture, and the carbon dioxide leaves at 1 atm and 60oC. The entropy change of carbon dioxide in the dehumidifying section is
(a) 22.8 kJ/kg·K
(b) 20.13 kJ/kg·K
(c) 0
(d) 0.13 kJ/kg·K
(e) 2.8 kJ/kg·K
