Physics involves the study of

Options

A. plants
B. humans
C. birds and animals
D. nature and natural phenomena

Explanation

**Step-by-Step Solution:**

1. **Understanding the Scope of Physics**: Physics is a branch of science that focuses on understanding the fundamental principles governing the natural world. It encompasses various aspects of nature and the interactions between different entities.

2. **Defining Nature and Natural Phenomena**: Nature refers to the physical world and everything in it, including living organisms, physical objects, and the environment. Natural phenomena are observable events that occur in nature, such as the behavior of light, sound, gravity, and various weather patterns.

3. **Examples of What Physics Studies**: Physics examines a wide range of topics, including but not limited to:
- The motion of objects (kinematics and dynamics)
- The properties of matter (solid, liquid, gas)
- Energy and its transformations (thermodynamics)
- Waves and vibrations (sound and light)
- Forces and interactions (gravity, electromagnetism)

4. **Conclusion**: Therefore, the study of physics is fundamentally about understanding nature and the natural phenomena that occur within it. This includes everything from the smallest particles to the largest galaxies, as well as the forces and laws that govern their behavior.

**Final Answer**: Physics involves the study of nature and natural phenomena.
