It is difficult to cook rice A. At the top of a mountain B. At the sea level C. Under a mine D. Same anywhere

The correct answer is: A. At the top of a mountain

The higher you go, the lower the air pressure. This means that the boiling point of water is lower.

So, if you try to cook rice at the top of a mountain, it will take longer for the water to boil, and the rice may not cook evenly.

Option B: At the sea level, the air pressure is normal, so cooking rice is the same as anywhere else.

Option C: Under a mine, the air pressure is much lower than at sea level. This means that the boiling point of water is even lower than at the top of a mountain. So, if you try to cook rice under a mine, it will take even longer for the water to boil, and the rice may not cook evenly at all.

Option D:

This option is not correct because cooking rice is not the same everywhere. The air pressure, altitude, and other factors can affect the cooking time and the final result.
