Acharacteristic curve graphically demonstrates the relationship between which of the following?
a. density and contrast
b. detail and distortion
c. density and exposure
d. contrast and exposure

C

Explanation:

on y-axis of characteristics curve there is density and on x-axis there is exposure, when exposure increases density also increases, it means there is direct relation between exposure and density.

A characteristic curve is a graph of the relationship between the quantity of exposure assumed a film and it's resultant density after processing.
