The term responsivity as it applies to a light detector is best described as
∙ A. the time required for the signal to go from 10 to 90 percent of maximum amplitude ∙ B. the ratio of the diode output current to the input optical power
∙ C. the ratio of the input power to output power
∙ D. the ratio of output current to input current
