The correct answer is B: 6 meters. The 6-meter band is best suited for communicating via meteor scatter. Meteor scatter propagation occurs when radio signals are reflected off the ionized trails left by meteors entering Earth's atmosphere. The 6-meter band (50-54 MHz) is in the optimal frequency range for meteor scatter. Higher frequencies (like 2 meters) work but require larger meteors. Lower frequencies (like 10 meters) work but are less efficient. 6 meters provides a good balance - the meteor trails are long enough and dense enough to effectively reflect 6-meter signals, making it the preferred band for meteor scatter communications. Contacts via meteor scatter are typically brief (seconds to minutes) as the meteor trail quickly dissipates.
