B. is the correct answer I think
The speed of a longitudinal wave will not be affected by the temperature of its surrounding. Base on the formula for the wave speed (applicable on longitudinal wave), wave speed ( speed in m.s 2) is equal to the distance of a wave (wavelenth in meter) travel over a unit of time (seconds) or wave speed is equal to distance of a wave times the frequency (hertz), temperature is not included in calculating the wave speed.
Hi, In my opinion, bat will be the most closely related to hawk.
Why?
This is because, when we consider the photo of a bat and a hawk, we notice the similarities like:-
• Wings- They have nearly the same short wings decreasing the area of contact with air and enabling higher flight area.
• Presence of small snouted beak-like structure and presence of less or more similar color.
• Both live in trees and are normally not companiable with humans.
• Hawks and bats are both having a similar anatomy, not body, I meant that they have similar positioning of organs like stomach, pancreas etc.
• They have the sense of locating prey miles away, enabling easier locating of food.
Hope this helps...

It should include the species of a rabbit. There are multiple types of rabbit and that would be considered the independent variable (where there are different things).
It should aloso include the environment; Are rabbits comfortable living in hot or cold weather areas?
