Classification (tableware – function): Three items are drinking vessels; one item is a flat dish for serving/eating. Identify the odd one out.

Introduction / Context:
Household-object classification commonly distinguishes items by function. Cup, tumbler, and jug are used to hold/pour liquids for drinking; a plate is used to serve/eat solid food and is not a vessel. The function boundary (container for liquids vs flat dish) creates a simple and widely understood odd-one-out scenario appropriate for quick reasoning checks.

Given Data / Assumptions:

• Cup → small drinking vessel.
• Tumbler → drinking glass.
• Jug → vessel for holding/pouring liquids.
• Plate → flat dish for food.

Concept / Approach:
Group by “designed to contain and/or pour liquids for drinking.” The three vessels form the majority class; the plate does not meet the containment function and is therefore the outlier.

Step-by-Step Solution:

Verification / Alternative check:
Attempt the sentence “Fill the ____ with water.” Works for cup, tumbler, jug; not for a plate in normal use.

Why Other Options Are Wrong:

Common Pitfalls:
None significant; this is a straightforward functional classification.

Final Answer:
Plate
