Introduction / Context:
Animal terminology frequently distinguishes between juvenile and adult stages. Understanding these labels enables quick classification in odd-one-out tasks.

Given Data / Assumptions:

• Kitten: a young cat.
• Colt: a young male horse.
• Fawn: a young deer.
• Stag: an adult male deer.

Concept / Approach:
Find the majority group (juveniles) and identify the outlier (adult).

Step-by-Step Solution:
Step 1: Label each term as juvenile or adult.Step 2: Kitten, Colt, and Fawn denote juveniles.Step 3: Stag denotes an adult; thus, it is the odd one out.

Verification / Alternative check:
Cross-check definitions in standard zoological/glossary sources; usage is consistent with common English.

Why Other Options Are Wrong:
Kitten/Colt/Fawn: All are juvenile terms and fit the majority.

Common Pitfalls:
Do not conflate species with life-stage terminology; the category distinction is age-based.

Final Answer:
Stag
