Question 15 in the morning session of the 2016 Chemistry exam was a bit incorrect

What does this average temperature difference refer to? If it is the average temperature difference for heat transfer, then the given values such as area and flow rate are not useful at all. Does anyone have a detailed solution?

The options for this question are exactly the same as those for the previous question; it seems that the question was copied incorrectly. Honestly, these real exam questions are really unreliable, full of errors

Is the condition regarding the heat transfer area redundant, or is there something more to it?
