The developing agent will only have an effect on the exposed silver halide crystals at recommended time-temperature

Indicate whether the statement is true or false

True. The developing agent reduces the exposed silver halide crystals to metallic silver but has no effect on the unexposed crystals at recommended time–temperatures. This is called "selective reduction," meaning that only the nonmetallic elements, the halides, are removed, and the exposed silver remains.
