Critical Reasoning

Hi, your help with the following question, I selected a) but it is not the correct answer. Can you explain me please. Thanks in advance,

Intense hurricanes only rarely strike large cruise ships at sea, since the ships' motility and weather-tracking abilities generally allow them to avoid hurricanes.

The performance of an automated navigation system in unexpected situations cannot be predicted.

Which of the following conclusions can most properly be drawn, if the statements above are true, about an automated navigation system on a cruise ship caught in a major hurricane?

a) At some point during its life, a cruise ship's automated navigation system would react inappropriately and might cause the loss of the ship.
b) The navigation system would be destroyed in a major hurricane.
c) The navigation system cannot distinguish between a major hurricane and a minor storm.
d) Whether the navigation system would perform as expected during a storm would depend on the strength of the storm.
e) The system's performance in the hurricane is uncertain, if the system's designers did not anticipate that the ships using the system would ever be in such a strong storm
