a. mu Leptons
b. Pentaquark
c. Heavy Electron
d. None of these

ANSWER: Pentaquark
Scientists at CERN's Large Hadron Collider announced the discovery of a new class of exotic subatomic particles called the pentaquarks. Pentaquark was first predicted to exist in the 1960s but, much like the Higgs boson particle before it, the particle eluded science for decades until its detection at the LHC.
