Answer

Brief Explanations:

  • Option A: Touching a looped wire to a battery creates a current (dynamic electricity), not static.
  • Option B: Pouring water over a conductor involves charge flow (not static buildup) and water is a conductor, not for static.
  • Option C: Rubbing two insulators (e.g., fur and rubber) transfers electrons, building static charge on insulators (since insulators don’t let charges move freely, charge accumulates).

Answer:

C. rubbing two insulators together
