The correct answer pertains to the requirement that a natural fiber parachute must have been packed within the last 60 days to be considered safe for use in an emergency. This time frame ensures the parachute's components are not compromised, thus maintaining its reliability and effectiveness for deployment.

Natural fiber parachutes tend to degrade over time, especially if they are exposed to environmental factors, such as moisture and sunlight, which can weaken the materials. By emphasizing recent packing, it ensures that the parachute has been properly maintained and remains in suitable condition for use.

The other options present misunderstandings about parachute regulations and usage. For instance, while FAA certification is crucial for many aircraft equipment, the specific reference to natural fiber parachutes in emergency situations isn't strictly tied to certification with an FAA label. The statement regarding adverse weather conditions is also misleading, as emergency parachute usage is governed by the parachute's condition rather than the weather. Lastly, the assertion that natural fiber parachutes are never permitted is incorrect; they can be utilized as long as they are within the specified packing period.
