Answer: A E

Explanation:

The Modulation and Coding Scheme (MCS) used by wireless stations is directly affected by the signal-to-noise ratio (SNR) and the frequency band. Higher SNR can lead to higher MCS values, which means better data rates. The frequency band can affect MCS due to different channel characteristics, such as the presence of interference and propagation properties, which are factors in determining data rates.
