Step 1: Concept
Understanding the components and their functions of various stringed and wind musical instruments.
Step 2: Meaning
List - I contains elements related to specific musical instruments: Bow-Violin, Toppi-Mridangam, Holes-Flute, Frets-Veena. List - II lists parts or features of these instruments: IV-Bow, III-Toppi, II-Holes, I-Frets.
Step 3: Analysis
Let's analyze each element from List - I and match it with the correct part in List - II:
1. Bow-Violin: The bow is a crucial component for playing the violin as it is used to draw across the strings to produce sound.
2. Toppi-Mridangam: Toppi refers to the small, decorative top piece of the mridangam, which is an important feature but not directly related to its function in producing sound.
3. Holes-Flute: Holes on a flute are essential as they control the pitch by changing the length of the air column when covered or uncovered.
4. Frets-Veena: Frets on a veena (or any stringed instrument) help in accurately tuning and playing specific notes.
Matching these, we get:
A. Bow-Violin: IV-Bow
B. Toppi-Mridangam: III-Toppi
C. Holes-Flute: II-Holes
D. Frets-Veena: I-Frets
Thus, the correct matching is A-IV, B-III, C-II, D-I.
Step 4: Conclusion
The given answer key correctly matches List - I with List - II based on the components and their functions in musical instruments.
Final Answer: (A)
