Final answer:
In the context of distracted driving, braking and all modalities are typically delayed because distractions impair the driver's ability to react promptly and process various cognitive and sensory functions.
Step-by-step explanation:
When considering distracted drivers engaged in auditory and visual tasks, the impact on braking and modalities typically results in b) Braking and all modalities are delayed.
Distracted driving is known to impair the ability of the driver to react promptly, which means that the time taken to initiate braking increases, potentially leading to longer stopping distances and a heightened risk of collision. Moreover, distractions can interfere with the driver's ability to accurately perceive and process information from various modalities such as visual and auditory cues, which are critical for safe driving. Thus, tasks that divert a driver's attention away from the road have been shown to delay the driver's reactions and impair the synchronization of different cognitive and sensory functions.
