The correct option is Rhinoceros and buffalo.
Explanation
The "Pashupati" seal (Seal 420), discovered at Mohenjo-daro, is a steatite seal depicting a seated figure often identified as "Proto-Shiva" or a yogi. This artifact provides significant insight into the religious beliefs and iconography of the Indus Valley Civilization.
Analysis of the Seal's Composition:
- The central figure is seated in a yogic posture on a low throne.
- The figure is surrounded by four wild animals:
- Right Side (Viewer's Perspective): An elephant and a tiger.
- Left Side (Viewer's Perspective): A rhinoceros and a buffalo.
- Additionally, two antelopes (or deer) are depicted beneath the seat.
Since the question specifically asks for the animals on the left side, the correct pair is the rhinoceros and the buffalo.
Key Takeaway: The Pashupati seal features a central deity flanked by an elephant and tiger on the right, a rhinoceros and buffalo on the left, and two antelopes below.
