Answer 2

Answer:

(b) Bird

Explanation:

Explanation for correct option:

Explanation for correct option:(b) Bird

Planes have been designed as birds to have a minimal wind resistance when they fly to overcome the disunion. Therefore, planes have been designed similar as to have a streamlined body to overcome the frictional force of air. Streamlined body of birds help them to move fluently through the air while flying. It reduces the air resistance during flying. It occurs when the fluid closest to the object sticks to its face, plying a force that opposes the object's stir. Numerous creatures, similar as birds and dolphins, and numerous machines, similar as aeroplanes and submarines, have streamlined bodies to reduce disunion drag as they move through either in air or water. So, aeroplanes are like birds.

Explanation for incorrect options:

Explanation for incorrect options:(a) Dog

This option is incorrect because dog does not have streamlined body so it produces air resistance and hence, aeroplanes are not like the shape of dog.

(c) Car

This option is incorrect because car does not have streamlined body so it produces air resistance and hence, aeroplanes are not like the shape of car.

(d) All of these

This is option is incorrect because option dog and car is wrong.

Therefore, option (b) is correct.
