  • There is at least one person sitting between Lillian and Lima;
  • Liyaqat is towards the right of Lima but not towards the right of Lalit;
  • Lalit is seated immediately next to Lillian; &
  • Lima is seated at one of the extreme corners of the bench.

Which of the following is definitely true?

  1. A.

    Lillian and Liyaqat are seated immediately next to one another.

  2. B.

    Liyaqat is seated at one of the extreme corners of the bench.

  3. C.

    There is at least one person seated between Lalit and Liyaqat.

  4. D.

    There is at least one person seated between Lalit and Lima.

Answer

D

Explanation

From left to right: Lima is at left end: [Lima, Liyaqat, Lalit, Lillian] or [Lima, Liyaqat, Lillian, Lalit]. In all possible valid arrangements, Lalit is separated from Lima by at least Liyaqat. Thus there is at least one person seated between Lalit and Lima.
