which horse finished second in a british group race, but was disqualified and placed second?

Question

a: centurius
b:creag-an-sgor
c:soba
d:rousillon

Answer 1

This was a tricky one, all four of them had run in a British Group Race and been disqualified, but apparently only Creag-an-Sgor was then placed second.

I was told this second hand, so can't guarantee it is 100% correct, but I know all of the horses were disqualified at some stage in their careers though.
