Which is the best example of a force counteracting Fp? using a dolly to push a box to another location two children pulling apart a wishbone a group of dogs pulling a dogsled across ice two people pushing a broken-down car up the road

Two children pulling apart a wishbone is the best example of a force counteracting Fp, because it involves the two children exerting a force in opposite directions. Instances of using a dolly to push a box to another location, a group of dogs pulling a dogsled across ice, two people pushing a broken-down car up the road involve exerting force in the same direction, so they are not examples of a force counteracting Fp.
