Seven varsity basketball players A, B, C, D, E, F and G are to be honoured at a special luncheon. The players will be seated on the dais in a row. A and G have to leave the luncheon early and so must be seated at the extreme right. B will receive the most valuable player’s trophy and so much be in the centre to facilitate presentation. C and D are bitter rivals and therefore, must be seated as far apart as possible. Who among C,D,F,G cannot be seated at either end?
