Correct Answer: B
Explanation
The Amateur Extra class license, the highest level of amateur radio certification, is rewarded with exclusive operating privileges on four major HF bands: 80\text{m}, 40\text{m}, 20\text{m}, and 15\text{m}. These bands are subject to a staggered privilege structure where General and Advanced class operators also have segments, but the lowest frequency portion of each of these bands is strictly reserved for Amateur Extra licensees.
The other HF bands (160\text{m}, 60\text{m}, 30\text{m}, 17\text{m}, and 12\text{m}) are structured so that all licensees (General and up) have either shared privileges or the bands do not have exclusive segments reserved only for Amateur Extra class operators. The exclusive segments, often just a small amount of spectrum at the bottom of the band, ensure that the most skilled operators have uncontested access to prime spectrum for very weak signal or international contacts.
