In the following question, four terms related to vehicles are given. Three are complete vehicles and one is only a part of a vehicle. Select the odd word from the given alternatives.

Introduction / Context:
This question is a simple classification based odd one out problem using everyday transport related words. It tests whether the learner can distinguish between whole vehicles and parts that make up a vehicle. Such questions are common in verbal and logical reasoning sections and rely mainly on general awareness of common objects rather than advanced mathematics.

Given Data / Assumptions:
- The options are Car, Cycle, Tyre, Truck, and Bus.
- Car, Cycle, Truck, and Bus are all names of complete vehicles used for transport.
- A Tyre is a component part that is fitted onto the wheel of many vehicles.
- We assume standard meanings of these terms as used in everyday language and road transport contexts.

Concept / Approach:
The main idea is to group items based on whether they represent a complete vehicle or only a part of a vehicle. Whole vehicles like cars, cycles, trucks, and buses are independent units that people can ride or drive. A tyre cannot be used alone for transport; it functions only as a part of these vehicles. The correct odd one out is therefore the term that does not represent a complete vehicle.

Step-by-Step Solution:
Step 1: Consider Car. A car is a full motor vehicle that people drive on roads.Step 2: Consider Cycle. A cycle, usually a bicycle, is a complete non motorised vehicle that a person can ride.Step 3: Consider Truck. A truck is a large motor vehicle designed to carry heavy goods.Step 4: Consider Bus. A bus is a large motor vehicle used to carry many passengers at once.Step 5: Consider Tyre. A tyre is a rubber component that fits around a wheel and helps the vehicle move smoothly on the road.Step 6: Since Car, Cycle, Truck, and Bus each refer to entire vehicles, while Tyre is only a part used in several vehicles, Tyre is clearly the odd one out.

Verification / Alternative Check:
We can verify this by imagining each item separately. If you have a car, cycle, truck, or bus, you can travel from one place to another. They are complete modes of transport. However, having only a tyre does not allow you to travel; it must be attached to a vehicle. This thought experiment confirms that Tyre falls into a different category from the others and is correctly chosen as the odd one out in this list.

Why Other Options Are Wrong:
Car is not the odd one out because it is a full vehicle similar in function to truck and bus, and like cycle it is used for transport. Cycle is also a complete vehicle, although non motorised, and so it still belongs with the other vehicles. Truck is a large goods vehicle and fits the transport category clearly. Bus is a passenger vehicle that again fits the same category. These four terms all refer to complete vehicles and therefore are not the odd ones in this problem.

Common Pitfalls:
Some learners may be tempted to choose Cycle because it is not motorised like car, truck, or bus. However, the pattern used in this question is completed vehicle versus component, not motorised versus non motorised. Another pitfall is to think that Tyre appears less important because it is smaller, but the real distinction is its role as a part, not a whole. Remember to classify items based on their functional category to answer such questions correctly in exams.

Final Answer:
Tyre
