Which statement about Morse code limitations is correct?

• A. Hard to translate, takes a long time, requires skilled operators, and can convey only limited information
• B. Completely easy to translate and requires no training
• C. Allows unlimited data transmission without error
• D. Is obsolete and never used

Answer: (A)

Morse code limitations come from how it works as a timing-based signaling system. Messages are built from short signals (dots) and long signals (dashes) that must be carefully timed and spaced, and decoded by listening or watching for these patterns. Because decoding relies on human perception and precise timing, it takes careful training to become proficient, and even then speed is relatively slow compared to modern digital methods. That combination—need for skilled operators, slower transmission, and limited information density—means Morse code can’t convey large amounts of data quickly or reliably in dynamic conditions. So the statement that captures these realities—hard to translate, takes a long time, requires skilled operators, and conveys only limited information—is the best fit. The other options describe things that Morse code doesn’t hold true: it isn’t completely easy to translate without training, it doesn’t offer unlimited, error-free data transmission, and while not as common today, it isn’t truly obsolete or never used.
