The Correct Option is C
Solution and Explanation
Radiometric resolution refers to the sensor's ability to distinguish different levels of brightness.
A 6-bit radiometric resolution means that the image can represent \( 2^6 \) gray levels.
\( 2^6 = 64 \)
Therefore, a satellite image with 6-bit radiometric resolution has 64 gray levels.
