Yes, A is correct. Because of the question mentions that it is a boundary. The level surface always parallels to the earth's surface. Still lake boundary is having not the same elevation. But having equal elevations at any point. That joined together form contour line.

Why would the boundary be a contour line? On maps, contour lines are typically shown at even intervals. What if the water surface is at elevation 137.2? This would not be a contour on a map. Water surface elevations are not shown as contours on a contour map.

The contour line is the correct answer. Because focus on the question he asking about line. Not asking about surface. If it's asked about surface than answer is level surface. If it's asked about the line then the correct answer is contour.

Boundary of any water body is taken as zero contour line (as mean sea level) and we know that free water tends to level itself, so when we talk about the surface of free water body that surface is a levelled surface.

Option C is correct because Boundary of the still lake is a contour line. And cross-section of still lake is a level surface.

For Boundary of water - contour.
Cross-section of still water -level line.
Limit of water level - horizontal level.
Cross-section of still water -level line.
Limit of water level - horizontal level.

The boundary of still water rep - contour line.
The surface of the water in a still lake or pond - Level surface.
The surface of the water in a still lake or pond - Level surface.

Still water means level surface, and contour has zig-zag surface, not plane. So that A is the correct answer.

Level surface is for still lake but for boundary it is contour line. So the given answer here is correct D.
