Phreatiline = The top flow line of a saturated soil mass, below which seepage takes place, is called the Phreatic line.
Flow Lines = are the paths which water particle follow in the course of seepage. Water flows from the point of higher head to low head.
Equipotential lines =are the lines formed by joining the points of same head or potential on the flow lines.

B is not correct because phreatic line is perpendicular to the slope of the upstream side of the dam. And equipotential lines are also perpendicular to the phreatic line.
So upstream slop represents an equipotential line. Hence A is the correct answer.

At the upstream slope of the earthen dam, there exists 100 per cent equipotential line on its surface.
As further equipotential lines are drawn with a subsequent drop in the head in the flow net mesh.

The shape of Phreatic line is parabola starting from the point of junction of the water level and the embankment with 90° angle.

Upstream slope is perpendicular to phreatic line. Moreover phreatic line is parabolic in nature and upstream slope is not.

'A' is the correct option. Equipotential lines are perpendicular to flow line.
