Answer - B - The unit used to measure the light sensitivity of a camera is Lux.

Key Takeaway: The light sensitivity of a camera is measured in lux (lumens). One lux is the equivalent of the amount of light produced by one candle measured at a distance of one meter. The lux rating on a camera indicates the minimum amount of light the camera needs to capture images clearly. Cameras that have a lux rating of less than 1.0 are capable of capturing images in very dim light. Most security cameras are in the range of 0.1 to 0.8 and are able to capture images in dim light.
