In a parallel flow heat exchanger operating under steady state, hot liquid enters at a temperature T_{h, in} and leaves at a temperature T_{h, out}. Cold liquid enters at a temperature T_{c, in} and leaves at a temperature T_{c, out}. Neglect any heat loss from the heat exchanger to the surrounding. If T_{h, in} >> T_{c, in}, then for a given time interval, which ONE of the following statements is true?

Entropy gained by the cold stream is GREATER than entropy lost by the hot stream

Entropy gained by the cold stream is EQUAL to the entropy lost by the hot stream

Entropy gained by the cold stream is LESS than the entropy lost by the hot stream

Entropy gained by the cold stream is ZERO
