This question evaluates logical deduction, constraint satisfaction, and basic combinatorial reasoning used to infer ordering from positional clues. Commonly asked to assess a candidate's ability to apply discrete math and spatial reasoning within the Statistics & Math domain, it targets conceptual understanding of constraints rather than practical implementation.

Four coworkers—A, B, C, and D—are standing in a single row facing north. The following clues hold: (

  1. A is somewhere to the left of C. (
  2. B is not at either end. (
  3. D stands next to exactly one of A or C. (
  4. There is exactly one person between A and B. Determine the exact order from left to right and explain your deduction steps.
