What is the focus of natural science?

The focus of natural science is on the study of the physical features of nature. Natural sciences encompass disciplines such as physics, chemistry, biology, and Earth sciences, all of which aim to understand the natural world through observation, experimentation, and the formulation of laws and theories. These sciences investigate the fundamental principles governing natural phenomena, including the structure and behavior of matter, the laws of motion and energy, ecological systems, and the processes that shape our environment.

In contrast, the other options pertain to different fields of study. The study of human behavior falls under the realm of social sciences and psychology. Ancient civilizations are examined through archaeology and history, which analyze historical societies and their cultures. Societal norms are the subject of sociology, focusing on the rules and expectations that govern social behavior. Therefore, the emphasis on the physical aspects of nature distinctly qualifies option B as the correct answer.
