Explanation: FCC rules, specifically Part 97.313(b), permit amateur radio stations to use up to 1500 watts peak envelope power (PEP) on most amateur bands. All the power levels listed in the options (0.1 W, 0.5 W, 1 W, 5 W, 25 W, 50 W) are well below this general limit and are therefore permitted. However, exam questions often seek the *most representative* or *common* scenarios. Option C, with "Low Power: 1 W, High Power: 25 W," describes a very typical and practical range of power settings found on amateur radio transceivers, particularly for VHF/UHF operations where many new licensees begin. 1 watt is a common low-power output for local contacts or conserving battery, while 25 watts is a widely used and effective "high power" setting for mobile and base station operations without pushing equipment limits or being unnecessarily powerful.
