Step 1: Define compounding
Compounding is the morphological process of combining two or more free morphemes (independent words) to create a new word (e.g., toothbrush, blackboard).
Step 2: Define "compounding of compounds"
This occurs when a compound word itself combines with another word to form a bigger compound. Example: blackboard (compound) + paint → blackboard-paint.
Step 3: Evaluate options
(A) Lighthouse tower — Lighthouse is already a compound (light + house). Adding tower forms a compound of a compound. ✔
(B) Skating board — compound word, but not compounding of compounds; it is simply activity + noun. ✘
(C) Boyfriend — simple compound (boy + friend), not compounding of compounds. ✘
(D) Walkman — blend/brand name, not compounding of compounds. ✘
\[
\boxed{\text{Correct Answer: (A) Lighthouse tower}}
\]

The 12 musical notes are given as \( C, C^\#, D, D^\#, E, F, F^\#, G, G^\#, A, A^\#, B \). Frequency of each note is \( \sqrt[12]{2} \) times the frequency of the previous note. If the frequency of the note C is 130.8 Hz, then the ratio of frequencies of notes F# and C is:
