Verified step by step guidance

1. Step 1: Begin by understanding the scope of biology as a scientific discipline. Biology is the study of life and living organisms, including their structure, function, growth, evolution, distribution, and interactions with their environment.
2. Step 2: Compare the provided options to the definition of biology. Eliminate choices that do not align with the study of living organisms and their interactions with the environment.
3. Step 3: Analyze the first option: 'The study of living organisms and their interactions with the environment.' This aligns directly with the definition of biology and is likely the correct answer.
4. Step 4: Evaluate the second option: 'The exploration of celestial bodies and the universe.' This pertains to astronomy, not biology, so it can be eliminated.
5. Step 5: Assess the third and fourth options: 'The analysis of chemical reactions in non-living matter' relates to chemistry, and 'The study of historical events and human societies' pertains to history or anthropology. Neither of these options aligns with the focus of biology, so they can also be eliminated.
