The theory that living organisms on the earth came from outer space is based on the study of

Options

B. Sedimentary rocks
C. Meteorites
D. Moon soil

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about a theory that suggests living organisms on Earth originated from outer space.

2. **Identifying the Relevant Theory**: The theory that explains this concept is known as the "Panspermia Theory." This theory posits that life did not originate on Earth but was brought here from elsewhere in the universe.

3. **Mechanism of Transfer**: According to the Panspermia Theory, life (in the form of spores or seeds) was transported to Earth via celestial bodies such as meteorites or asteroids.

4. **Evaluating the Options**: The question likely provides multiple-choice answers. We need to identify which option aligns with the Panspermia Theory:
- Option A: Igneous rocks (not related)
- Option B: Sedimentary rocks (not related)
- Option C: Meteorite (related to the theory)
- Option D: (not specified in the transcript)

5. **Selecting the Correct Answer**: Based on the explanation, the correct answer is **C: Meteorite**, as it directly relates to the mechanism by which life could have been transported to Earth.

**Final Answer**: The theory that living organisms on Earth came from outer space is based on the study of **Meteorites**.
