Where is the best place to mount a camera with a fixed iris?

A camera with a fixed iris is best mounted outside in a shadowed position. Fixed iris lenses do not adjust to changes in light levels, making them less suitable for environments with varying lighting conditions. By placing the camera in a shadowed position, you minimize the impact of direct sunlight and glare, which can cause overexposure and poor image quality. Therefore, the correct answer is C.
