Analogy — Part to whole (unit relation):\nMinute : Hour :: ? : ?\n\nSelect the pair that keeps the same “smaller unit : larger unit” relationship.

Introduction / Context:
“Minute : Hour” is a classic unit relation where the first term is a standard subunit of the second (60 minutes = 1 hour). The correct completion must preserve a fixed, conventional subdivision ratio rather than a vague aggregation.

Given Data / Assumptions:

• A minute is a defined fraction of an hour.
• We seek another currency/time-like subunit with a codified conversion.
• Choices include mass/aggregation metaphors and discrete systems (currency, sets).

Concept / Approach:
The tightest parallel is the currency subunit: in the Indian system, 100 paise = 1 rupee (historically standard). This matches the “subunit-of” relationship precisely and unambiguously, like “minute” to “hour”.

Step-by-Step Solution:

Verification / Alternative check:
Just as you can compute hours from minutes by a constant factor, you can compute rupees from paise by a constant factor.

Why Other Options Are Wrong:

• Drop : Ocean — Metaphorical aggregation; not a standardized subunit.
• People : Crowd — A set aggregation, not a unit system.
• Cup : Tea Set — Component vs set; no fixed quantitative conversion.
• None of these — invalid because a correct pair exists.

Common Pitfalls:
Choosing any “part-of” relation without ensuring a formal, countable conversion like time/currency units.

Final Answer:
Paisa : Rupee
