The correct answer is option 2, Samudragupta. The title `Indian Napolean` has been attached to him. The term `Indian Napoleon` is used to describe Samudragupta because of his military conquests and his ability to expand the Gupta Empire. Samudragupta was a skilled warrior and a great strategist, much like Napoleon Bonaparte. He is known for his successful campaigns and his patronage of arts and culture during his reign. During his rule, the Gupta Empire reached its zenith in terms of territorial expansion and cultural achievements. Although other rulers like Chandra Gupta Maurya, Chandragupta-I, and Harshavardhana were significant in the history of India, the title `Indian Napoleon` specifically refers to Samudragupta`s military prowess and achievement.
