Study the following information carefully and answer the question. Eight persons—A, B, C, D, E, F, G, and H—sit around a square table. Four sit at the middle of the sides and face inward, while four sit at the corners and face outward. G sits second to the left of C. Three persons sit between D and B. H sits opposite A but does not sit at the middle of a side. D sits second to the left of A. F sits second to the right of C. E sits immediately to the right of B. Who sits immediately to the right of D?

Correct answer: B
Concept
In a mixed-facing seating arrangement, left and right are read from each seated person’s own viewpoint. At a square table, corner seats face outward and side-middle seats face inward, so their clockwise and counterclockwise directions are reversed. A valid answer therefore requires fixing all seats before reading an immediate-neighbor relation.
Application
Number the seats 0 through 7 clockwise and place A at corner seat 0; choosing a starting seat only fixes the rotation and does not change any relationship.
H is opposite A and is not at a side-middle, so H is at corner seat 4. Because A faces outward, A’s left runs counterclockwise; D, second to A’s left, is at corner seat 6.
Three persons sit between D and B, so B is opposite D at corner seat 2. B also faces outward, making B’s immediate right the next clockwise seat; therefore E is at side-middle seat 3.
The remaining side-middle seats are 1, 5, and 7 for C, F, and G. Since C faces inward, C’s second-left position is two seats clockwise and its second-right position is two seats counterclockwise.
If C were at seat 1, G would need occupied seat 3. If C were at seat 5, F would need occupied seat 3. The only consistent case is C at seat 7, which places G at seat 1 and F at seat 5.
The unique clockwise order is therefore A, G, B, E, H, F, D, C. D is at outward-facing corner seat 6, so D’s own right runs clockwise to seat 7, occupied by C.
Cross-check
The final order gives H opposite A, B opposite D with three persons on either arc, D second to A’s left, E immediately to B’s right, G second to C’s left, and F second to C’s right. Every clue holds with no collision, confirming that C sits immediately to D’s right.
