The confirmation of the presence of Higgs boson justifies option 4, which is the mass of fundamental particles. The Higgs boson is a subatomic particle that was discovered in 2012 through experiments conducted at the Large Hadron Collider (LHC) in CERN. It is a crucial component of the Higgs mechanism, which explains how particles acquire mass.
According to the standard model of particle physics, fundamental particles gain mass by interacting with the Higgs field, which is mediated by the Higgs boson. The Higgs field pervades the entire universe and interacts with particles as they move through it, giving them mass.
Therefore, the confirmation of the Higgs boson`s existence confirms the concept of the Higgs mechanism and validates the fundamental understanding of how particles acquire mass. This confirmation was a significant milestone in particle physics and supports the predictions of the standard model.
It is important to note that the other options (option 1, option 2, and option 3) do not align with the specific role of the Higgs boson in relation to the mass of fundamental particles. Therefore, the correct answer is option 4.
