    Solution

    C sits exactly in the centre of the row and faces the one who likes White. Only one person sits between J and the one who likes White. So J can be either extreme right or extreme left end of the row. So here we get following two cases: (1) When J sits extreme right end of the row. J faces one of the immediate neighbours of the one who likes Black. Only two people sit between A and the one who likes Black. A faces the one who likes Brown. D is an immediate neighbour of E. So only two places left for D and E. so I can be either at 2nd or 3rd to the right of the 2nd row.   Now we know that G is not an immediate neighbour of I and faces the one who likes Red. I does not like Brown. G does not sit at the extreme end of the line. It means G sits 2nd to the left end of the 2nd row. So I sits 2nd to the right end of the 2nd row. I faces immediate neighbours of E. so E sits left end of the 1st row. F faces the one who likes Violet. F does not like White. So F sits left end of the row and H sits at the centre of the row.    The one who likes Pink sits to the immediate right of the person who likes Orange. J does not like Pink. So this case is not valid. (2) When J sits extreme right end of the row J faces one of the immediate neighbours of the one who likes Black. Only two people sit between A and the one who likes Black. A faces the one who likes Brown. D is an immediate neighbour of E. So only two places left for D and E. so I can be either at 2nd or 3rd to the left end of the 2nd row. Now we know that G is not an immediate neighbour of I and faces the one who likes Red. I does not like Brown. G does not sit at the extreme end of the line. It means G sits 2nd to the right end of the 2nd row. So I sits 2nd to the left end of the 2nd row. I faces immediate neighbours of E. so E sits right end of the 1st row. F faces the one who likes Violet. F does not like White. So F sits right end of the row and H sits at the centre of the row.  The one who likes Pink sits to the immediate right of the person who likes Orange. J does not like Pink. The one who likes Green sits opposite to the person who sits left of the person who likes Pink. The one who likes Cream faces north.
