Correct option is D
In optical communication, one of the key advantages is its high bandwidth, meaning it can carry more data at faster rates compared to traditional electrical or radio-based communication systems. Additionally, optical communication is immune to electric noise since it uses light, not electrical signals, to transmit data, which prevents interference from electrical sources. However, magnetic noise is generally not a factor in any communication system, whether optical or electrical, as it does not typically interfere with either system. Therefore, the absence of magnetic noise is not a distinct advantage of optical communication. The real benefits are increased bandwidth, high speed, and immunity to electric noise, making it the preferred choice for high-speed internet and data transfers.
