    Correct Answer
    A. Increase
    Explanation
    The detector quantum efficiency refers to the ability of a detector to convert incident photons into electrical signals. An increase in the detector quantum efficiency means that the detector is becoming more efficient at converting photons into signals, resulting in a higher sensitivity and better performance. This could be achieved through improvements in the detector design, materials, or technologies used.
