Raj is trying to make a diagram to show what he has learned about nuclear fusion.Is his diagram correct, and if not, how could he fix it?

Question illustration
A
Yes, he should leave it as is because one atom of He plus energy results in two atoms of H and heat and pressure.
B
No, he should place energy on the right and heat and pressure on the left.
C
No, he should place the He atom and energy on the right, and the H atoms and heat and pressure on the left.
D
No, he should place the He atom on the right and the H atoms on the left.
