To find Brian's current cholesterol level after a 6% reduction, we first need to calculate 6% of his original level, which is 280.
1. Calculate 6% of 280:
\[
6\% \text{ of } 280 = \frac{6}{100} \times 280 = 0.06 \times 280 = 16.8
\]
2. Now, subtract this amount from the original cholesterol level:
\[
\text{New Cholesterol Level} = 280 - 16.8 = 263.2
\]
Since we are asked for the approximate cholesterol level, we can round this to 263.
Thus, the answer is:
\[
\text{C. } 263
\]
