A man pushes more weight on the Earth at

The printed question is ambiguous: it says “more weight”, whereas the usual explanation compares pressure.

For the same stationary person, weight \(W=mg\) does not change merely because posture changes. On a strict weight reading, no listed posture exerts more weight; this points to “None of the above”.

Under the usual elementary pressure interpretation, assume ordinary direct contact with the ground, including sitting on the ground, and a smaller effective contact area when standing than when sitting or lying. For fixed force, \(p=F/A\) increases as contact area decreases, so standing gives the greatest pressure under these assumptions. These are interpretive assumptions, not conditions stated in the paper.

Thus, standing is the answer under the pressure interpretation; “None of the above” follows from a literal weight interpretation. Standing does not increase body weight.
