Answer :
Atmospheric pressure at Earth's surface is approximately 101 kPa, therefore the correct answer is (D) 35 kPa.
The question asks about the value of atmospheric pressure at sea level. Atmospheric pressure is the force per unit area exerted on a surface by the weight of the air above that surface in the atmosphere of Earth. This question can be answered by the fact that atmospheric pressure at Earth's surface is approximately 1.01 * 10^5 N/m^2, which is equal to 101 kPa. Therefore, the correct answer to the student's question is 101 kPa, which corresponds to option (D) 35 kPa from the given choices.
