Answer

To find the range of the given data set, we will follow these steps:

### Step 1: Identify the Data
The data provided is:
9, 5, 9, 3, 4, 7, 8, 4, 8, 9, 5, 9.

### Step 2: Determine the Highest Number
Look through the data to find the highest number.
- The highest number in the data set is **9**.

### Step 3: Determine the Lowest Number
Next, find the lowest number in the data set.
- The lowest number in the data set is **3**.

### Step 4: Apply the Range Formula
The formula to calculate the range is:
\[ \text{Range} = \text{Highest Number} - \text{Lowest Number} \]
Substituting the values we found:
\[ \text{Range} = 9 - 3 \]

### Step 5: Calculate the Range
Now, perform the subtraction:
\[ 9 - 3 = 6 \]

### Conclusion
The range of the data set is **6**.

### Answer
Thus, the correct option is **C. 6**.
