From the figure:
In P, the inner shape touches the boundary of the outer shape, suggesting a tangent relationship. So, P corresponds to Within Tangent (2).
In Q, the inner shape is clearly within the outer shape but not touching any edge. This fits the definition of Within Borders (1).
In R, the inner shape is strictly and symmetrically inside with no contact to the edges, best fitting Within Strict (3).
Hence, the correct mapping is:
P:2; Q:1; R:3
