  • A.ratholing
  • B.bridging
  • C.mass flow
  • D.surcharge

Answer: A

Correct answer: ratholing

A rathole is a stable vertical channel that empties above the outlet while the material around it stands still, held up by its own cohesion. It is a funnel flow phenomenon: the stagnant material stays in place indefinitely, which matters where the product can spoil or where the bin’s working capacity has effectively been lost.
