Answer: It is D (The average kinetic energy of the particles)
Explanation:
I don’t know what you mean by “give me a reason to live as well” but I think you should live because even though it is hard sometimes there will always be someone that cares about you and would never know what life would be like without you even if you may not have found that person yet they are somewhere in the world and you just need you keep going and find that special person! Hope this helps!

Answer B is the correct answer
We know that kinetic energy , where m is the mass of object and v is the velocity of object.
In this case only velocity is the variable, mass remains constant.
So point having higher velocity has higher kinetic energy.
When it leaves the racket, the ball will be having a certain height, but just before it reaches the ground it will not having any height. So maximum velocity of ball is at that time when it reaches just above the ground.
So option B is the correct answer.
