The correct answer is option 'C' - Boat.


- A boat is a watercraft that is specifically designed to travel across rivers, lakes, and other bodies of water.
- It is a vehicle that is buoyant and is capable of floating on water.
- Boats are generally powered by oars, sails, or engines, which help in propelling them through the water.
- They come in various sizes and shapes, depending on their purpose and the specific body of water they are meant to travel on.
- Boats are commonly used for transportation, fishing, recreation, and even for emergency services.


- Trains, buses, and cars are vehicles that are primarily designed for land transportation.
- Trains run on railway tracks and are used for long-distance travel, commuting, and transporting goods and passengers.
- Buses are road vehicles that are designed to transport a large number of passengers between different locations.
- Cars are personal vehicles that are used for individual or family transportation on roads.


- In the given options, the only vehicle that is specifically designed for traveling across rivers is a boat.
- Trains, buses, and cars are not suitable for traveling across rivers as they are not designed for water travel.
- While some trains and cars can be transported across rivers using specialized methods like ferries or bridges, they are not inherently capable of traveling across rivers on their own.

Therefore, the correct answer is option 'C' - Boat.
