Correct Answer: D

Explanation:

Explanation:
Encryption, with a strong key, is the most secure method for protecting the information on the flash drive. Carrying the flash drive in a portable safe does not guarantee the safety of the information in the event that the safe is stolen or lost. No matter what measures you take, the chance of losing the flash drive still exists. It is possible that a courier might lose the flash drive or that it might be stolen.
