C)a particle with negative mass.
D)All of the above.

Question

Quizplus · Accepted Answer

The Dirac theory predicted that a positron would be a particle with the same mass as an electron but with opposite charge. This is known as an anti-particle. Option A is incorrect because a negative electron in a negative energy state is not a physically meaningful particle. Option C is also incorrect because particles cannot have negative mass according to current understanding of physics. Option D is incorrect because only option B is accurate.
