Football : Hockey : Tennis — Select the tightest correct category that encapsulates these activities and choose the most accurate label from the options.

Introduction / Context:
This analogy focuses on activity classification. Football, hockey, and tennis are organized competitive activities played under codified rules, typically by trained participants and often in formal competitions. The aim is to locate the best singular label from the options to represent their shared nature precisely.

Given Data / Assumptions:

• Football, hockey, and tennis are structured competitive activities.
• A single option should label them without ambiguity.
• We prefer the specific activity type rather than labels about participants or environments.

Concept / Approach:
Differentiate the activity from the people who perform it. Athletes describes participants, not the activities themselves. Aquatic is an environment label that does not apply to all three. Indo appears to be an unrelated distractor. Games straightforwardly captures the essence of each listed item. While sport could also work, the provided options use Games, which is acceptable and accurate in standard reasoning tests.

Step-by-Step Solution:
1) Identify each listed term as a competitive activity with rules.2) Compare options to see which classifies the activities themselves.3) Select Games as the best fitting label among the given choices.

Verification / Alternative check:
Substitute Sports for Games conceptually. The intent remains correct. Because Games is the available precise category among the options, it is the right selection that preserves meaning without introducing errors.

Why Other Options Are Wrong:

• Athletes: Refers to people, not the activities named.
• Indo: Not a meaningful category for these items in this context.
• Aquatic: Only some forms of hockey are on ice and not aquatic; football and tennis are not aquatic activities.

Common Pitfalls:
Confusing the performers with the performance. Choose the category that labels what the words directly denote. Here the words are the activities, and Games labels them accurately and compactly.

Final Answer:
Games
