To solve this question, we need to identify the top view of a hill based on the given horizontal cross-sections. The diagram shows these cross-sections at various altitudes, indicating the shape of the hill as seen from above.

The concept here involves understanding contour lines or contour mapping, where each line represents a constant height. The closer these lines are to each other, the steeper the hill is at that point.

From the given diagram:

• As height increases, the ovals get smaller, which implies a slope that tapers off as it reaches the top.
• The most probable top view will have the smallest oval near the center, surrounded by larger ovals as the height decreases going outward.

Upon examining the options:

• Option P: Ovals are becoming larger outward, but their density doesn't suggest a uniformly tapering hill.
• Option Q: Shows a clear center with the smallest oval surrounded by larger ovals, mimicking a gradual elevation to a peak.
• Option R: Similar to P, does not suggest a consistent tapering towards a single peak point.
• Option S: Less consistent tapering pattern, does not resemble a top view of a single topped hill.

Thus, Option Q correctly depicts the top view of the hill.

Conclusion: The correct answer is Q as it best represents the gradual tapering and pointed top view of the hill as seen from above.
