Correct Answer: Surface tension
Solution : The correct option is Surface tension .
Ballpoint pens operate based on the principle of surface tension. The ink's surface tension determines how effectively it spreads over the pen's ball. If the surface tension is too high, the ink won't spread properly over the ball. Conversely, if the surface tension is too low, the ink may become smeared or blotchy on the paper.
