Answer & Explanation
The correct answer is Option C: 12 hours.
Permits to Work are valid for a specified time to ensure that the work conditions haven't changed. A 12-hour period is the standard maximum, requiring a new risk assessment and re-authorization to ensure safety if the task continues beyond a single shift.
