B. magnetic and gravitational fields
C. gravitational, electric, and magnetic fields
D. electric field only
Answer:Option C. gravitational, electric, and magnetic fields
Explanation:
An electron is a negatively charged particle having mass, m = 9.1 × 10⁻³¹ kg and charge, q = -1.602 × 10⁻¹⁹ C. Gravitational field is created all bodies having mass. Hence, a moving electron also creates gravitational field.
A charged body creates electric field around it. And when the charged body moves, it also creates magnetic field. Hence, a moving electron creates gravitational field, electric field and magnetic field.
Therefore, the correct answer is option C.
