Option 1 : Electric field 

CONCEPT:

  • Cyclotron: A cyclotron is an apparatus in which atomic and subatomic charged particles are accelerated by an alternating electric field while following a spiral or circular path in a magnetic field.
  • A cyclotron is used to accelerate, positively charged particles but negatively charged particles and neutrally charged particles   (e.g neutron) cannot be accelerated in the cyclotron.

EXPLANATION:

  • Cyclotron can accelerate positively charged particles through the electric field only. 
  • The working of the cyclotron is based on the fact that a positively charged particle can be accelerated to sufficiently high energy with the help of similar values of the oscillating electric field by making it to cross the same electric field time and again with the use of a strong magnetic field.

So option 1 is correct.
