Answer» Correct Answer - Option 4 : Oil based

The correct answer is Oil based.

  • Hungarian-born László Bíró created the ballpoint pen in modern times. 
  • While working at the newspaper, he realized that the ink used on newsprint dried quickly and was generally smudge-free.
  • The key to their success was a combination of a thick, sticky ink and a tiny ball bearing.
  • This ball-and-socket mechanism allows the ball to roll around easily on paper while sealing the ink from the air so it doesn’t dry out.
  • The ink used in ballpoint pens is oil-based and dries faster than other types of ink.
  • Rollerball pens use the same design as ballpoint pens but with water-based ink.
  • Marker pens come in four types of ink: pigment, water, oil and alcohol-based.
