A Charged Particle Is Placed at Rest in the Middle

A charged particle is placed at rest in the middle of a vacuum chamber, an enclosure that has been emptied of all matter. Consider some point X near a particular corner of the chamber. Neglecting all influences other than the charged particle, what can be said regarding electric fields and magnetic fields at point X?

A) There is both an electric field and a magnetic field at X.
B) There is no electric field at X but there is a magnetic field at X.
C) There is an electric field at X, but no magnetic field.
D) There is neither an electric field nor a magnetic field at X.
E) It is impossible to answer this question without knowing what kind of charge the particle has.
