Selected Answer: A
While confirming that data is transported in locked tamper-evident containers (option C) is also a good practice to prevent unauthorized access or tampering during transportation, encryption provides an additional layer of security by rendering the data indecipherable to unauthorized parties.

Selected Answer: A
Encryption ensures that even if the physical security measures fail and the tapes fall into the wrong hands, the data on the tapes would still be unreadable and useless to unauthorized individuals

Encryption = confidentiality, the question is about Integrity, locked tamper box, will protect the tapes to be damaged during transportation.

in my opinion A could be right. The question is about integrity of DATA and not the physical security of the tapes. Even if the tapes are transported in tamper evident containers, this will physically protect the tapes and in event of tamper will leave behind an evidence. However, if the data on tapes is encrypted, the data integrity will be preserved during as well as after the transport.

encryption can protect the confidentiality of data, but it does not necessarily ensure data integrity
