Using a combination of symmetric and asymmetric key encryption,Sofia sent a report to her home office in Indiana.She received an e-mail acknowledgement that her report had been received,but a few minutes later she received a second e-mail that contained a different hash total than the one associated with her report.This most likely explanation for this result is that
A)the public key had been compromised.
B)the private key had been compromised.
C)the symmetric encryption key had been compromised.
D)the asymmetric encryption key had been compromised.

The different hash total suggests that the report may have been tampered with during transmission, indicating that the symmetric encryption key may have been compromised. Asymmetric key encryption provides authentication and integrity, but it is not designed for large amounts of data encryption, which is why a symmetric key encryption was likely used for the actual transmission of the report. If the public or private keys were compromised, it would likely prevent the successful transmission and decryption of the report, rather than just altering the hash total.
