The correct answer should be a cross-flow heat exchanger.

However, the surface area for parallel and counter-flow heat exchangers will be the same but more than cross-flow.

It's Only in counter flow.

In case of evaporating & conditioning, the logarithemic temperature is all cases. So, Area will also be the same.

Because in the phase transformation process parallel flow and counter flow heat exchanger becomes identical in nature hence all of these is the correct answer.

Evaporating & condensing independent of type of flow.
