Well the answer of your question is "wide belt of school bag''
This is because the definition of pressure say that P =F/A
here P is the pressure and A is the area.
As the pressure is inversly proportional to the area so the more the area less will be the pressure produced and less area means the more pressure production. So out of all the options wide belt of school bag have the largest area which means it produced minimum pressure or less pressure,

The correct answer is - the Wide belt of the school bag.
All the other 3 options i.e., needle, sharp knife and spear have narrowing ends which are supposed to be sharp and hence they put on more pressure and pain when it touches the skin.
However, the wide belt of the school bag has a wide surface area. As per the formula, P = f/a, the pressure is inversely proportional to area.
Therefore, the wider the surface area, lesser the pressure. So, from the given options, the wide school belt produces less pressure than others.
