Which ISO setting is typically used to minimize digital noise and maximize sharpness?

Explanation:
Lower ISO minimizes digital noise because the sensor’s signal is amplified less, which keeps fine details crisper and preserves more tonal nuance. Noise at higher ISOs tends to blur fine edges and degrade perceived sharpness, especially in shadows and textured surfaces. So when the goal is to maximize sharpness and reduce noise, you start from the base ISO—the lowest native setting your camera offers—and only raise it if you must for exposure or motion reasons. In the given options, choose the one that represents that base, lowest sensitivity, rather than higher sensitivities that add noise.
