Hello!
I am not given any options, but I can explain the question to you.
A biotic factor is anything that is living in the ecosystem, such as animals, plants, fungi, and bacteria.
An abiotic factor is anything that is not living but the ecosystem needs to thrive, such as sunlight, oxygen, good temperature, living space, etc.
For example, let's say we had options below.
A. Sunlight
B. Living Space
C. Moss
D. Oxygen
As you can see, all of our options are beneficial to an ecosystem, but moss is the only one that is living. In this scenario, our answer would be C. Moss, as it is a biotic but not an abiotic factor.
I hope this helps!

Answer:
A) Pre-australopithecinerobust.
B) Australopithecinesgenus Homo.
Explanation:
Pre-australopithecinerobust.
The few findings indicate that he walked with his back straight, but the shape of the foot, with the big toe directed inward (as in the hands) instead of being parallel to the others, indicates that he should walk leaning on the outside of his feet and he couldn't travel great distances
Australopithecinesgenus Homo.
The first hominids that are certain that they were completely biped are the members of the Australopithecus genus, this type of hominin thrived in the wooded savannas of East Africa between 4 and 2.5 million years ago with remarkable ecological success, as evidenced by the radiation he experienced, with at least five different species scattered from Ethiopia and Chad to South Africa.
