Explanation:
The means of land transport mentioned in the options are bullock cart, ship, bus, and car. Out of these options, the correct answer is 'B' - Ship. Ships are not a means of land transport, but rather a means of water transport. Ships are used primarily for transporting goods and people over long distances across oceans, seas, and rivers. They are designed to float on water and are powered by engines or sails.

Land Transport:
Land transport refers to the movement of people, animals, and goods from one place to another on land. It plays a crucial role in facilitating trade, commerce, and transportation of goods and people within a country or region. Land transport can be further classified into various modes, including:

1. Bullock Cart:
- A bullock cart is a traditional mode of land transport still used in some rural areas.
- It consists of a simple cart that is pulled by one or more domesticated bulls or oxen.
- Bullock carts are primarily used for carrying agricultural produce, firewood, and other goods over short distances.

2. Bus:
- Buses are a popular means of public transportation.
- They are designed to carry a large number of passengers and operate on predefined routes.
- Buses are commonly used in cities, towns, and rural areas to transport people for various purposes, such as commuting to work, school, or leisure activities.

3. Car:
- Cars are private vehicles used for personal transportation.
- They are designed to accommodate a small number of passengers and provide flexibility in terms of routes and destinations.
- Cars are widely used for daily commuting, travel, and transportation of goods over short to medium distances.

In summary, while bullock carts, buses, and cars are all means of land transport, ships belong to the category of water transport.
