Answer is cHow can it be d?How can the birds have powerful tail?If they had, they wont be able to fly up in the sky with heavy bodies.

Ans 17:

Class : Class 5
ans should be D

Ans 18:

Class : Class 5
The correct option is D and I have proof:-Streamlined body of birds help them to move easily through the air while flying. It reduces the air resistance during flying.There are only a few muscles in the trunk and the tail, but they are very strong and are essential for the bird.Powerful = Strong

Ans 19:

Class : Class 5
In the solution, they show that a strong tail is gonna hinder flight. Seriously, guys? It's a no brainer, and if it hasn't been taught in school, logical reasoning can be applied. Of course a strong tail would be heavier. Why not? If a person is strong, he is heavy. It's simple- more mass= more weight. Come on. Everyone knows this. It's just logic science!

The region of partial (iii), that is the (iv) reaching the earth is too large and too faint to be visible to us.
