Assume the four people are seated around the four sides of a square table facing the center (North, East, South, West):
Place Murali at the North seat (facing South). Murali's left is to the East.
Since Rahul is sitting to the left of Murali, Rahul is at the East seat.
The remaining two positions are West and South.
If Arul is at the West seat (facing East), Arul's right is to the South, where Srinivas must be seated.
Thus, the seating arrangement around the table is:
The opposite pairs are:
Murali and Srinivas (North and South)
Rahul and Arul (East and West)
Among the given options, Srinivas and Murali are seated opposite each other.
Hence, the correct option is (C).
