HOLA!!
_______
HERE YOUR ANSWER WITH REASON IS
ANSWER
b) School bag with a strip of cloth band.
REASON
We know a simple physics formula that is
Pressure = Force / area
P is inversely proportional to area
which shows that when the area is large , the pressure is less and if the area is small, the pressure is more.
Thin means ----> less area
Thick or wide --> massive area
If we need to carry it easier, the pressure must be less.
Therefore for less pressure we chose the school bag with a strip of wide cloth band.
