33: i think it’s b

the answer is to check all of them! they all apply well at least i think so!

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
