Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Correct option should be (2) that is, Upstream direction. Arch dam are mostly curved and the water pressure is directed to the convex side of the dam(they resist the water pressure on a pronounced scale).The water pressure is distributed from the upstream face of the dam to the abutment edges of the dam. So clearly the convex side of wall faces upstream. Go through the image attached below for more deeper insights.
