The Armstrong method is primarily associated with the synthesis and design of communication systems, specifically in relation to frequency modulation techniques. In this context, the correct association for the use of the Armstrong method is:

### Correct Answer
**d. C** (SSB-RC, which refers to Single Sideband, Reduced Carrier)

### Explanation
The Armstrong method facilitates the generation of single sideband (SSB) signals, which are more bandwidth-efficient and have better power efficiency than double sideband (DSB) signals. The reduced carrier version of SSB is particularly efficient for long-distance communication, minimizing the power wasted in the carrier frequency while still allowing for effective demodulation at the receiver's end.

Hence, the Armstrong method is most accurately linked to SSB with reduced carrier in FM applications.
