Step 1: Concept
Round-robin fixtures are a method where each participant plays against every other participant. Intramural activities take place within an institution's premises. Extramural activities occur outside the institution. Run for Unity is a specific event name that may have its own context but often refers to unity-building exercises.
[List - II] describes different methods and purposes:
Cyclic method: A scheduling technique used in round-robin fixtures.
To promote brotherhood: An aim of team-building or community activities.
"Within the walls": Refers to activities happening inside an institution's premises.
Outside the boundary wall: Describes extramural activities.
Step 2: Meaning
We need to match each fixture type from List - I with its corresponding purpose or method from List - II based on their definitions and typical uses in sports and games.
Step 3: Analysis
1. Round-robin Fixture (A) is best matched with Cyclic method (I), as the cyclic method is a scheduling technique used for round-robin fixtures.
2. Intramural (B) activities are typically "Within the walls" of an institution, so B matches with II.
3. Run for Unity (C) aims to promote brotherhood among participants, aligning it with purpose B-III.
4. Extramural (D) is defined as outside the boundary wall, which corresponds to D-IV.
Therefore, the correct matching is:
A-I
B-II
C-III
D-IV
Step 4: Conclusion
The given answer A matches all the fixture types correctly with their respective purposes or methods from List - II.
Final Answer: (A)
