Option d is the correct answer. Ustad Mansur/Mansoor was honored with the title "Nadir-ul-asra" (Unrivaled of the era) by Jahangir. While he created paintings during the reign of Jahangir's father, Akbar, his exceptional works truly flourished under Jahangir's patronage. Although celebrated for his natural history depictions, he also applied his artistic talents to portraying individuals in diverse manuscript illustrations.
