A Correct answer
Explanation

The seal() method signature includes both the data and timestamp parameters, throwing SecurityException because cryptographic sealing operations can fail. The timestamp is essential for implementing expiration, as described in the seal() functionality. Option B incorrectly specifies EncryptionException - security API methods throw SecurityException to signal security-related failures.
