Explanation:
Detailed explanation-1: -So, the correct option is ‘Precambrian, Palaeozoic, Mesozoic, Cenozoic’.
Detailed explanation-2: -Hadron Epoch. The Hadron Epoch lasted from 10^-6 seconds until one second (finally there!). The universe was now around 1 trillion degrees which allowed quarks to combine and form hadrons. Hadrons are subatomic particles made up of quarks, anti-quarks, and gluons.
Detailed explanation-3: -The history of the universe since the time of the Big Bang is divided into six epochs, corresponding to chaos, the hadron epoch, and the lepton epoch, which collectively make up the radiation era, and the atom epoch, the galaxy epoch and the stellar epoch, which make up the matter era.
