Step 1: Use the seating and direction clues.
David faces South.
Vipul faces West.
Vipul and Ahmad are partners (opposite).
So, Ahmad faces East.
Step 2: Carrom is played in a square — partners sit opposite.
If David faces South, the person opposite to him must face North.
From the given orientation, we deduce:
Vipul (West), Ahmad (East), David (South) → So the remaining player, Santosh, must be facing North.
