The rapid appearance of symptoms associated with Norovirus typically occurs within a few hours after exposure, making the choice that states "Hours" the correct answer. Norovirus is known for its quick onset, with symptoms usually manifesting between 12 to 48 hours after exposure to the virus. This characteristic is part of what makes Norovirus a common cause of outbreaks, particularly in crowded environments like restaurants and cruise ships.

In contrast, the other options reflect much longer time frames. The minute time frame would be too swift given the nature of the virus and its typical progression. Days would also extend beyond the usual symptom onset period. Weeks or months is unrealistic for Norovirus infection as it generally causes acute symptoms and does not linger in the body for extended periods. Understanding the typical incubation period is crucial for effective food safety management and outbreak prevention.
