Find the odd word (office/stationery vs place): Select the option that is not a stationery item or writing supply.

Introduction / Context:
This classification contrasts tangible stationery supplies with a physical/organizational place. Three items are common materials or tools used for writing; one is a location or organizational concept.

Given Data / Assumptions:

• Ink: writing medium.
• Paper: writing/printing substrate.
• Pen: writing instrument.
• Office: a place/room/organizational unit, not a stationery item.

Concept / Approach:
Group by functional role in writing tasks versus location.

Step-by-Step Solution:

Verification / Alternative check:
Ask: Can you put it in a pencil box or stationery cabinet? Ink, paper, pen → yes; office → no.

Why Other Options Are Wrong:
They are all writing-related consumables or tools.

Common Pitfalls:
Letting workplace association mislead you—“office” is connected to stationery but is not itself stationery.

Final Answer:
Office
