Final Answer:
a. True. Top Secret, Secret, and Confidential information typically require different methods of transmission.
Step-by-step explanation:
The classification of information as Top Secret, Secret, or Confidential indicates varying levels of sensitivity and importance. Each classification comes with specific security requirements, including different methods of transmission. Top Secret information, being the most sensitive, usually involves highly secure channels such as encrypted communication or secure courier services. Secret information also requires secure transmission methods but may have slightly less stringent requirements than Top Secret. Confidential information, while still sensitive, may be transmitted through standard secure channels.
In summary, the statement is true, as different classifications necessitate distinct and appropriate methods of transmission based on the level of sensitivity and confidentiality.
Option A is the answer.
