Answer:
d) beaks and claws
Explanation:
Birds have many physical attributes that help them fly in the air. They include a lightweight body, streamlined boat shaped body, and wings made of feather to flap through the air.
Though birds' beaks and claws are important factors for survival and catching prey, they are not necessarily the factors which help them fly. However, beaks are considered aerodynamic and hydrodynamic because most of them are coned shaped.
So option D is the correct answer.

"Oil spills affect water in a variety of ways. When oil is released into water, it does not blend with the water. Oil floats on the surface of salt and fresh water. Over a very short period of time, the oil spreads out into a very thin layer across the surface of the water. This layer, called a slick, expands until the oil layer is extremely thin. It then thins even more. This layer is called a sheen and is usually less than 0.01 mm thick."
