If the person who faces D likes White colour, then C likes which of the following colour?

We have, Only one person sits between A and the one who faces the one who likes white, who doesn’t sit at the ends of the row. D sits immediate right of the one who faces the one who likes white From this condition, there are two possibilities Again we have, Only one person sits between Q and the one who faces D. P is the only neighbour of the one who faces the one who likes yellow, who doesn’t face Q. Again we have, C sits second to the left of the one who faces the one who likes red, which is not liked by R. The one who likes green sits to the left of C, who doesn’t like orange. D neither likes blue nor white. As many persons sit to the right of B as to the left of the one who likes orange from the above condition, case 1 gets eliminated. Hence, case 2 shows the final arrangement. So final arrangment-
