Solution

The correct option is C A is true, but R is false.
Passive sensors gather radiation that is emitted or reflected by the object or surrounding areas. Reflected sunlight is the most common source of radiation measured by passive sensors. Examples of passive remote sensors include film photography, infrared, charge-coupled devices, and radiometers. Thus the sensor device cannot work independently but require good sunlight source for better results.
