*Question G0B06:
Which of the following is covered by the National Electrical Code?*  

*Correct Answer is  C: Electrical safety of the station*  

### AI Response: (may contain errors)  

The correct answer to the question is:

**C: Electrical safety of the station**

### Explanation:

1. **Why the correct answer is correct:**
   - The National Electrical Code (NEC) is a set of standards for electrical wiring and safety in the United States. It covers the installation of electrical equipment to ensure safety and prevent hazards such as electrical fires and shock. This includes guidelines for grounding, circuit protection, and proper installation practices in amateur radio stations.

2. **Why the other choices are incorrect:**
   - **A: Acceptable bandwidth limits**  
     Bandwidth limits are related to the technical specifications of radio communications and are governed by the Federal Communications Commission (FCC) regulations, not the NEC.
   
   - **B: Acceptable modulation limits**  
     Modulation limits pertain to the methods of encoding information onto a carrier wave and are also regulated by the FCC. The NEC does not address modulation techniques.
   
   - **D: RF exposure limits of the human body**  
     RF exposure limits are determined by guidelines set by organizations like the Federal Communications Commission (FCC) and the Institute of Electrical and Electronics Engineers (IEEE), not the NEC. The NEC focuses on electrical safety rather than RF exposure.

### Summary:
- The NEC is primarily concerned with electrical safety, making option C the correct choice. The other options relate to regulatory aspects outside the scope of the NEC.
