The correct answer is **C. Radio waves can penetrate the atmosphere.**
Radio waves are used for space communication primarily because they can travel through the Earth's atmosphere with relatively little attenuation, allowing for effective transmission over long distances. They are also suitable for carrying information and can be easily generated and detected with available technology. While it's true that radio waves do not require cables (B) and can penetrate some materials like walls (D), the key reason for their use in space communication is their ability to propagate through the atmosphere.
Option A is incorrect because there are other electromagnetic (EM) waves used for communication (like microwaves, infrared, etc.), but radio waves are particularly well-suited for the task.
