The correct option is Bisons and elephants.
Explanation
The rock shelters of Bhimbetka in Madhya Pradesh contain a continuous sequence of paintings ranging from the Upper Palaeolithic period to the Medieval period. These paintings are classified into seven distinct periods based on style, theme, and colour. Period I corresponds to the Upper Palaeolithic phase.
Detailed Analysis:
- Period I (Upper Palaeolithic): The paintings from this earliest phase are characterized by linear representations of huge animal figures. The artists predominantly used green and dark red colours.
- Subject Matter: The animals depicted in this period are typically large and imposing, such as bisons, elephants, tigers, rhinoceroses, and boars.
- Elimination of other options:
- Camels and horses: Horses are generally associated with later periods (such as the Chalcolithic or Historic periods), and camels are not native to the Central Indian prehistoric landscape.
- Lions and giraffes: Giraffes are not found in the Indian subcontinent during this geological epoch in the context of rock art.
- Buffaloes and yaks: Yaks are specific to the Himalayan region and are not found in the Central Indian plateau.
Key Takeaway:
Upper Palaeolithic paintings at Bhimbetka are distinct for their depiction of massive animal figures (Bisons, Elephants) using green and dark red pigments, contrasting with the smaller, dynamic hunting scenes of the subsequent Mesolithic period.
