C-14 has a half life of

Options

A. 11520 yrs
B. 2880 yrs
C. 5760 yrs
D. none of these

Answer

To determine the half-life of Carbon-14 (C-14), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Half-Life**:
- Half-life is the time required for a quantity to reduce to half its initial value. In the case of radioactive isotopes, it is the time taken for half of the radioactive atoms in a sample to decay.

2. **Identify the Half-Life of C-14**:
- The half-life of Carbon-14 is a well-established scientific fact. It is known that C-14 decays over time, and its half-life is approximately 5,760 years.

3. **Application of Half-Life**:
- This property of C-14 is utilized in carbon dating, which is a method used to determine the age of organic materials (like fossils and wood) by measuring the remaining amount of C-14 in the sample.

4. **Conclusion**:
- Therefore, the half-life of Carbon-14 is 5,760 years.

### Final Answer:
The half-life of C-14 is 5,760 years.
