Answer: The correct answer is the streamlined body.
Explanation: Streamlined body is any shape which provides buoyancy and it helps in less friction or reduces it so it is easier to travel in fluid or air for example fishes due to their streamlined body they can eaisly survive in water and move easily due to less friction and for fishes having a streamlined body that is smooth helps save energy it would otherwise have to expend swimming and in the same way airplanes fly in the sky or air due to less friction which gives them drag to push forward and also ships in water also move due to some reason as they also drag which is a force that slows down motion; friction drag is a special kind of a drag. Some other examples include birds that have a streamlined body to make their flight easier through the air. Snakes have a streamlined body to assist them to move forward because a streamlined body is a shape where the head and tail are smaller than the middle portion of the body. Such a body when traveling through a fluid or gaseous medium overcomes the friction caused by air and water.
