The above left is a simplified strength-distance graph of four fundamental interactions, also called fundamental forces or interactive forces. The above right is the Standard Model of elementary particles, with the fermions in the first three columns, the gauge bosons in the fourth column and the Higgs boson in the fifth column. Which of the following statements is correct?
a) The strong interaction is the strongest inside the atomic nucleus.
b) The weak interaction works only within a very short distance.
c) Electromagnetic interaction and gravitation work in almost infinite distance.
