Classification – Domestic/working animals: identify the odd one out based on typical use. Three are common draught or riding animals; one is primarily a pet and not used for draught work. Which option is different? Options: Camel, Horse, Bullock, Cat.

Introduction / Context:
Animal-use classification distinguishes working/draught species from companion pets. The majority here are traditionally used for transport, riding, or pulling loads.

Given Data / Assumptions:

• Camel: transport/draught in arid regions.
• Horse: riding/transport.
• Bullock (ox): draught animal for carts/ploughing.
• Cat: primarily a companion/pet, not a draught animal.

Concept / Approach:
Group by primary historical/typical human use: draught/riding vs pet/companion.

Step-by-Step Solution:
Tag Camel/Horse/Bullock as working animals.Tag Cat as a pet with no draught role.Hence, Cat is the odd one out.

Verification / Alternative check:
Cross-cultural usage records consistently place camels, horses, and oxen in transport/agriculture roles.

Why Other Options Are Wrong:
Camel/Horse/Bullock: All are typically used for riding or pulling loads.

Common Pitfalls:
Avoid edge cases like therapy animals or circus roles; the standard, widespread function is intended.

Final Answer:
Cat
