Which of the following correctly lists the lowest frequency band to the highest frequency band?

MF (Medium Frequency) occupies 300 kHz to 3 MHz, HF (High Frequency) occupies 3 to 30 MHz, VHF (Very High Frequency) occupies 30 to 300 MHz, and UHF (Ultra High Frequency) occupies 300 MHz to 3 GHz - correctly sequencing from lowest to highest. Each successive ITU band designation shifts the upper boundary by a factor of 10, making the ordering systematic and unambiguous.

This lists bands from highest (UHF) to lowest (MF), which is the reverse of the required lowest-to-highest order.

HF (3-30 MHz) is higher in frequency than MF (300 kHz-3 MHz), so placing HF before MF incorrectly reverses those two adjacent bands.

VHF and UHF are both higher in frequency than MF and HF, making this arrangement completely out of sequence.

This repeats the same error as choice C by placing HF (3-30 MHz) before the lower-frequency MF band (300 kHz-3 MHz).
