Nobel prize-winning physicist Peter Higgs, who passed away at the age of 94, proposed the existence of which particle in 1964 that helps explain how other particles acquire mass?

Correct option is D

Peter Higgs predicted the existence of the God particle, formally known as the Higgs boson, in 1964. This particle explains how other subatomic particles gain mass, which is fundamental to the formation of matter in the universe. The particle was experimentally confirmed in 2012 at CERN's Large Hadron Collider.
