The real answer of your question is the "wide belt of the school bag"
The reason is that the pressure depends on two things force and Area
As we know that Pressure = Force/Area
So the pressure is actually inversly proportional to the area which meant the lesser the area more will be the pressure and more area would mean the less pressure. Out of the given options in the question the wide belt of school have the more area so it will produce less pressure.

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