The typical range of ASA (American Standards Association) ratings for color film used in investigations generally falls between 25 and 1600. ASA ratings reflect the film's sensitivity to light, with lower numbers indicating less sensitivity and higher numbers indicating greater sensitivity. In the context of investigations, a range of 25 to 1600 is practical because it allows for the use of various films adapted for different lighting conditions typically encountered in investigative scenarios.

For instance, films with lower ASA ratings are beneficial in very bright lighting conditions, while those with higher ratings are useful in lower light situations. The range of 25 to 1600 covers a spectrum that allows investigators to capture images in various environments they may encounter during evidence collection. In contrast, other ranges listed in the choices either extend too far beyond typical operational needs or don't sufficiently cover the necessary sensitivity variations for investigative purposes.
