Orthogonal Frequency Division Multiplexing (OFDM) achieves the highest data rates among the options due to its ability to divide a single data stream into multiple parallel sub-streams, each modulated on separate frequencies. This method allows for efficient utilization of the available bandwidth and reduces the effects of interference and fading, particularly in environments where multipath propagation occurs.

OFDM's structure enables it to maintain high data rates by using a large number of closely spaced orthogonal subcarriers, allowing it to transmit data simultaneously over these carriers without interfering with each other. This contrasts with other modulation techniques, which may struggle with high data rates under similar conditions.

In environments where high data throughput is critical, OFDM is commonly employed in various applications, such as Wi-Fi, digital broadcasting, and LTE cellular systems. It represents a significant advancement in digital communication compared to traditional methods, making it optimal for achieving maximum data transfer rates in complex communication scenarios.
