The supportive premises for the thesis statement are A) 1, 2, and 3.
Explanation:
A thesis statement is comprised of one or two sentences intended to convey the author's viewpoint regarding the subject covered in the text, serving as guidance to keep the author focused. In Jack London's excerpt from "The Human Drift", the thesis indicates that the unfolding narrative will relate to how humanity has progressed in finding increasingly efficient methods of killing.
Premises are the assertions that should uphold and back the thesis statement. Accordingly, any premise that illustrates the development of human killing techniques and the diversity of targets will effectively support the thesis. This is exactly what sentences 1, 2, and 3 achieve. They discuss how humans kill to establish dominance; how weaponry was developed prematurely in human history; and how human capability has advanced to the extent of eliminating microorganisms.
