Although since its inception in the 1970s, the Standard Model has accurately predicted the existence of a range of particles, including the Higgs boson,
discovery of whom in 2012 at CERN electrified the scientific community, it cannot explain many conundrums such as what is dark matter, a theoretical form of matter believed to account for approximately 85% of the matter in the universe, and why the Higgs boson possesses the mass that it does.
(A) discovery of whom in 2012 at CERN electrified the scientific community, it cannot explain many conundrums such as what is dark matter, a theoretical form of matter believed to account for approximately 85% of the matter in the universe,
(B) which was discovered in 2012 at CERN electrified the scientific community, it cannot explain a number of several conundrums such as what dark matter, a theoretical form of matter believed to account for approximately 85% of universe’s matter,
(C) whose discovery in 2012 at CERN electrified the scientific community, it cannot explain several conundrums such as what dark matter, a theoretical form of matter that is believed to account for approximately 85% of the matter in the universe, is
(D) discovered in 2012 at CERN and electrified the scientific community, it may not explain several conundrums such as dark matter, a theoretical form of matter that is believed to account for approximately 85% of the matter in the universe,
(E) whose discovery in 2012 at CERN electrified the scientific community and cannot explain several conundrums such as dark matter is a theoretical form of matter believed to account for approximately 85% of the matter in the universe
