Answer:
The correct answer is option A-standing upright allowed for sightlines over tall grasses and savannah shrubbery.
Explanation:
Bipedalism or walking upright on two legs departed the hominids- Neanderthals and Homo erectus from four-legged apes. Many reasons were given to support the bipedalism of hominids like:
1. They needed to stand over tall grass to minimize the body exposure to the sun in savannah.
2. They needed to stand over tall grass to increase the sightlines to gather foods for themselves especially females and young ones which required hands to be free.
Thus, option A is the correct option.
