None of the above.
All the above are traits of the Human animal but your questioner seems to think natural selection tends towards man, it doesnt.
There are more insects than men so nature seems to prefer six legs.
There are more single celled animals than insects so nature prefers no legs at all
the question, or your examiner is flawed.

Binocular vision is most favored with the most groups of animals, whether predator or prey.
