B) erect posture

* Actually, erect posture was taking place while the brain size was enlarging (to be able to withstand a task [going from quadriped to biped] was thought to be of a large magnitude for a small brain to be able to handle).. But erect posture was what triggered the increase in the brain size.. Makes sense?
