In a shady area that receives little sunlight, a plant with larger, broader leaves is typically better adapted to absorb the limited light available. Therefore, without seeing the specific pictures of the leaves, I would suggest that the plant with the largest and broadest leaves among W, X, Y, or Z is most likely to survive in such conditions.
If you can provide more details on the characteristics of each plant's leaves, I can help determine which one is most suitable for a shady area.
