The Homo ergaster occupy Africa 1.6 million years ago. Therefore, option A is correct.
The oldest early humans known to have had proportions similar to modern humans, with relatively long legs and shorter arms compared to the size of the torso, are the early African Homo erectus fossils (also known as Homo ergaster).
At the onset of the lower Pleistocene and the lowering of the environment, Homo ergaster, sometimes known as the "working man," is an extinct species of hominid (or subspecies, according to some authorities) that existed throughout eastern and southern Africa between 1.9 and 1.4 million years ago.
Thus, the Homo ergaster occupy Africa 1.6 million years ago. Therefore, option A is correct.

The loss of chloroplasts would have a direct impact on a green plant's ability to carry out photosynthesis, which is the process by which plants convert light energy into chemical energy.
Photosynthesis is the process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy, which is stored in the form of organic compounds such as sugars, starches, and cellulose. This process occurs within specialized organelles called chloroplasts, which are found in the cells of green plants and algae. Without chloroplasts, a green plant would not be able to carry out photosynthesis and generate the chemical energy needed for growth and survival. As a result, the plant would gradually weaken and die as it was unable to produce enough energy to maintain its cellular processes.
Hence, the loss of chloroplasts would have a direct impact on a green plant's ability to carry out photosynthesis.
