Mosaic vision refers to the type of vision exhibited by compound eyes, where each individual optical unit functions independently to capture and process visual information. In cockroaches, this type of vision is continuously operational, meaning it is active both during daylight and nighttime conditions.

Unlike apposition vision, which relies on high light levels and is more effective during the day, mosaic vision in cockroaches allows them to perceive their surroundings and detect movement throughout the day and night. The compound eyes of cockroaches provide a wide field of view and are well-suited for detecting potential threats, locating food sources, and navigating their environment.
Hence, the correct answer is option 3.
