Classification (transport): Three are non-motorized or animal/hand-drawn modes of transport; one is a motorized hired vehicle. Identify the odd one out.

Introduction / Context:
Verbal classification questions often contrast items by a single salient feature. Here, each option names a common means of short-distance transport. Three are non-motorized or animal/hand-drawn; one is motorized and commercially hired. The task is to spot the motorized outlier.

Given Data / Assumptions:

• Rickshaw: generally a cycle- or hand-pulled vehicle in many cities (ignore motorized variants for this basic reasoning test).
• Tonga: a horse-drawn carriage.
• Cart: a hand-pulled or animal-drawn vehicle used for goods or people.
• Taxi: a motor vehicle for hire (metered or app-based).

Concept / Approach:
Group items by propulsion: motorized vs non-motorized/animal-powered. The single motorized, hire-based passenger vehicle is the odd one out.

Step-by-Step Solution:

Verification / Alternative check:
Consider licensing/fare: taxis require registration and charge fares; the others traditionally do not involve a motorized engine or regulated fare meters in the baseline sense.

Why Other Options Are Wrong:

Common Pitfalls:
Confusing auto-rickshaw (motorized) with rickshaw. In classic reasoning sets, “rickshaw” implies cycle/hand variant unless specified otherwise.

Final Answer:
Taxi
