Answer:
The correct answer is option A, An accelerating electric point charge (electron) emits electromagnetic waves
Step-by-step explanation:
An accelerating electric charged particle produces electromagnetic waves. The accelerating charged particle produces magnetic and electric field whose magnitude is changing continuously. Thus a changing electric field produces magnetic field and a changing magnetic field produces electric field. This changing electric and magnetic field produces electromagnetic wave which are able to move through a vacuum space and thus need no medium to travel
