Logical possibility that an assertion, hypothesis or a theory can be contradicted by , an observation or the outcome of a physical experiment is

Options

A. Law
B. Hypothesis
C. Fact
D. Falsifiability

Answer

To solve the question, we need to identify the term that describes the logical possibility that an assertion, hypothesis, or theory can be contradicted by observation or the outcome of a physical experiment. Here’s the step-by-step solution:

### Step-by-Step Solution:

1. **Understanding the Question**:
- The question asks for a term that describes the ability of a hypothesis or theory to be disproven through observation or experimentation.

2. **Identifying Key Concepts**:
- The key concepts here are "assertion," "hypothesis," "theory," "contradicted," "observation," and "physical experiment."

3. **Defining Falsifiability**:
- Falsifiability is a principle introduced by philosopher Karl Popper. It states that for a theory to be considered scientific, it must be able to be tested and potentially disproven by evidence.

4. **Applying the Concept**:
- If an assertion or hypothesis can be contradicted by empirical evidence or experimental results, it is said to be falsifiable. This means that there exists a possibility to prove it wrong.

5. **Conclusion**:
- Therefore, the logical possibility that an assertion, hypothesis, or theory can be contradicted by observation or the outcome of a physical experiment is called **falsifiability**.

### Final Answer:
The correct term is **falsifiability**.
