Answer: (D)

Verified step by step guidance

1. Understand 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. Compare the options provided in the question. The study of physical forces and motion is the focus of physics, not biology. Similarly, the study of celestial bodies and the universe falls under astronomy, and the study of chemical reactions and compounds is primarily the domain of chemistry.
3. Identify the correct focus of biology. Biology specifically deals with living organisms and their interactions with the environment, which distinguishes it from other scientific disciplines.
4. Recognize that biology encompasses various subfields, such as ecology, genetics, physiology, and molecular biology, all of which contribute to understanding life and its processes.
5. Conclude that the correct answer is: 'The study of living organisms and their interactions with the environment,' as this best describes the primary focus of biology as a scientific discipline.
