Solution

The correct option is D P-4, Q-2, R-1, S-3
At the peak of the blast furnace, low temperature is there. Here at $900 ° K$ , the ore comes to the furnace through the top and mixes with ' $C O$ ' from the bottom.
At $1200 ° K$ , flux formation takes place from limestone.
At $1500 ° K$ , the ore is heated with carbon at the bottom to give Iron and ' $C O$ '.
At bottom of furnace, $200 ° K$ occurs, and here Carbon reacts with oxygen to give Carbon mono oxide
