Free Space Optics (FSO) is the correct choice for communication between the 6th floor of one building and the 10th floor of another building due to its capability for line-of-sight data transmission over relatively short distances. FSO uses light to transmit data, making it an ideal solution for connecting buildings that are close to each other but cannot rely on cabled connections.

In urban environments where buildings may obstruct traditional wireless communications, FSO provides a high-bandwidth alternative without the need for physical wiring. The technology operates in the optical spectrum, allowing it to transmit large amounts of data quickly and with minimal latency, which is crucial for maintaining efficient communication between different floors of separate buildings.

Furthermore, FSO doesn’t involve interference from radio frequencies, making it more reliable in areas with high electronic noise. Its installation is also comparatively easier and less expensive than running cables through multiple floors and walls.

While other methods like Wi-Fi and radio frequency can transmit data wirelessly, they may not provide the same level of performance in terms of bandwidth and distance, especially in a multi-building setup with potential interference. Satellite communication, on the other hand, operates over much larger distances and is not economical or practical for connecting floors of adjacent buildings because of
