A,B,C Correct answer
Explanation

Higher ISO settings increase the camera sensor's sensitivity to light, allowing more light capture (A). This increased sensitivity comes with the trade-off of more digital noise or grain in the image (B). The benefit is that you can use faster shutter speeds in low-light conditions without underexposing the image (C). All three are correct - higher ISO gives you light sensitivity and shutter speed flexibility but introduces more noise. Photographers constantly balance ISO against noise levels to get optimal exposure.
