Edexcel particles question

For Q6, why is the answer C? I thought as E=mc^2, large energies are required to create mass as 9*10^16 J would be required to create a kg of mass, and more so for large masses

What we're looking for here is that you comprehend the principles of the answers. Let's look at each of the choices and why high energies might or might not be needed in the case of the Large Hadron Collider (LHC).
The Large Hadron Collider accelerates protons to high energies and then makes them collide. Why do physicists try to make these collisions happen?
A.) Annihilate hadrons: When particles and antiparticles collide, what occurs? Do you require super high energies for this, or can we have it in lower energies? Think about the conservation of basic properties.
B.) Collide hadrons: That's what the LHC does. Must particles be traveling very quickly when they collide? What occurs at higher energies that does not occur at lower energies?
C.) The creation of particles with large mass calls for a respect for Einstein's equation, E=mc^2. Trying to make a heavy particle, what do you need lots of?
D.) Single quarks can be produced as hadrons, like protons, are made up of quarks. Quarks are not found alone under normal circumstances. What would it take to isolate a quark? Would this undertaking require a large amount of concentrated energy?
By comparing these aspects for both choices, it is possible to determine which process does not require the very high energies of the Large Hadron Collider (LHC).

Here is my 2 cents!
