Analogy — Plant source: Tea : Leaves :: Coffee : ? Select the plant part/source that relates to “Coffee” as “Leaves” relate to “Tea”.

Introduction / Context:
The analogy concerns the consumable plant part used to prepare the beverage. Tea is made from processed young leaves (and buds) of Camellia sinensis; coffee is brewed from roasted seeds (beans) of Coffea species.

Given Data / Assumptions:

• Tea → Leaves.
• Coffee → ?
• Options mix levels (whole plant vs part; functional noun “stimulant”).

Concept / Approach:
Match “specific plant part used” on both sides. For coffee, the edible/brewed part is the seed (commonly called the coffee bean, which is botanically a seed).

Step-by-Step Solution:

Verification / Alternative check:
Botanical references: coffee beans are the seeds within the coffee cherries.

Why Other Options Are Wrong:

• Plant: Not parallel to “Leaves”.
• Leaves: Not used for coffee brewing.
• Stimulant: Describes effect, not plant part.
• None of these: Invalid because “Seeds” fits.

Common Pitfalls:
Choosing “Plant” due to category confusion; analogy seeks the same granularity as “Leaves”.

Final Answer:
Seeds
