Which value describes pulsed duty cycle as indicated in the source?

Explanation:
Duty cycle reflects how much of each treatment cycle the device is actually on. A continuous setting means the device is on for the full cycle (100%). In the source, pulsed duty cycle values are specified as 20% or 50%, meaning the device is on for only 20% or 50% of each cycle and off for the rest. That’s why the option stating “20,50 is pulsed” best matches the reference. The 100% value describes continuous use, while the other numbers are not the pulsed values indicated by that source.
