    Note that the Newton's 3rd law pair act on different bodies, whereas the Newton's 1st law pair act on the same body.

    Both the weight and the Normal reaction act on the apple, whereas the Reaction and Push act on different bodies (reaction acts on apple, Push acts on ground)

    Not relevant to OP but that's a pretty shocking question IMO - when I was doing A level I was told not to bother memorising which of newtons laws said what because it was just useless rote learning of an arbitrary list order... it was understanding what they meant and the ability use that understanding to perform calculations which would be tested.
