Solution

The correct option is B Plasma
  • Plasma is a 4th state of matter.
  • It is created by a process called Ionization which involves adding energy to a gas so that some of its electrons leave its atoms. It results in negatively charged electrons, and positively charged ions.
  • Unlike the other states of matter, the charged particles in a plasma reacts strongly to electric and magnetic fields.
