The correct option is Ustad Mansur.
Explanation
Mughal miniature painting reached its zenith under the patronage of Emperor Jahangir, who possessed a keen interest in naturalism. The depiction of flora and fauna became a specialized genre during his reign, characterized by scientific precision and aesthetic refinement.
Detailed Analysis:
- Ustad Mansur is Correct: Ustad Mansur was the leading nature painter at Jahangir's court. The emperor conferred upon him the title Nadir-ul-Asr ("Wonder of the Age"). Mansur is celebrated for his detailed studies of birds, animals, and flowers. His most famous works include the painting of a Falcon (1615), the Dodo, and the Zebra. The falcon depicted was a gift from Shah Abbas I of Persia to Jahangir; when the bird died, Jahangir ordered Mansur to paint its likeness to preserve its memory.
- Abul Hasan is Incorrect: Abul Hasan was a contemporary of Mansur and a favorite of Jahangir, who gave him the title Nadir-uz-Zaman ("Wonder of the Time"). However, his expertise lay primarily in portraiture and complex court scenes, not natural history.
- Basawan is Incorrect: Basawan was a pre-eminent painter during the reign of Akbar (Jahangir's father). He was known for his use of western techniques like perspective and shading, primarily contributing to manuscripts like the Akbarnama and Razmnama.
- Manohar is Incorrect: Manohar was a distinguished painter active during the reigns of Akbar and Jahangir. While he produced exquisite portraits and court scenes, he is not the primary artist associated with the specific genre of bird and animal studies that defines Mansur's legacy.
Key Takeaway:
Ustad Mansur is the definitive Mughal artist associated with the realistic depiction of flora and fauna during Jahangir's reign, holding the title Nadir-ul-Asr.
