Long-range communications are capable of ______.

Long-range communications are capable of ______.

• A. Providing only voice transmissions over short distances
• B. Providing data transmissions only via fiber
• C. Providing data and voice transmissions when ships are over the visible horizon
• D. Providing data and voice transmissions when ships are within direct view

Answer: (C)

Long-range communications rely on signals that go beyond what you can see directly, using methods that extend past the line of sight. For ships, this means you can transmit both data and voice even when the vessels are beyond the visible horizon, typically via high-frequency radio with ionospheric skip or satellite links. The statement describing data and voice when ships are over the visible horizon captures this capability, whereas the other options limit to short distances, fiber media, or direct-view scenarios that do not reflect long-range reach.
