Solution
The correct option is A very slow
Rusting is several steps chemical process, the rough surface of iron get rusted than even surface because in rough surface the tiny holes absorb the moisture (forming tiny water ponds) this water absorbs carbon dioxide from air forming the carbonic acid, this acid is responsible for rusting but it is weak acid so process is very slow.
