A red brick wall of length 5 m, height 4 m and thickness 0.25 m has a temperature on the inner surface of 40 degree C and on the outer surface of 110 degree C. The thermal conductivity of the red brick is k = 0.70 W/mK. What will be the temperature at an interior point of the wall, 20 cm from the inner wall?
Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).

Assertion (A): Counter flow heat exchanger is more effective than a parallel flow heat exchanger.

Reason (R): For same temperature limits of hot and cold fluids, the overall heat transfer coefficient of counter flow heat exchanger is more than parallel flow heat exchanger.

In light of the above statements, choose the correct answer from the options given below.
