FM/IR/IL refers to technologies used to deliver ALD signals. Which option correctly expands this acronym?

Explanation:
This question tests decoding of the abbreviations used to describe technologies for delivering ALD signals. Each part maps to a standard term: FM is Frequency Modulation, IR is Infrared, and IL is Induction Loop. So the correct expansion is Frequency Modulation / Infrared / Induction Loop. The other options mix in terms that aren’t the standard meaning for the third piece (Induction Loop), such as Induction Link, or swap in fiber-based modulation concepts that don’t fit the given IL. Infrared can be written as Infrared or Infra Red, but IL consistently stands for Induction Loop in this context.
