The vehicles carrying inflammable fluids usually have metallic chains touching the ground :

Options

  1. ATo protect tyres from catching dirt from ground
  2. BTo alert other vehicles
  3. CIt is a custom
  4. DTo conduct excess charge due to air friction to ground and prevent sparking

Correct answer

D. To conduct excess charge due to air friction to ground and prevent sparking

Step-by-step solution

Static charge is developed due to air friction. This can result in combustion. So, metallic chains is used to discharge excess charge.
