Option 1: (D), (A), (B), (C) -> Mauryan empire ended (185 BCE), Gupta rule began (320 CE), Pallavas rose (~6th century CE), Arabs conquered Sind (712 CE) - correct chronological sequence.
Option 2: (C), (D), (A), (B) -> Places Arab conquest (712 CE) before Mauryan end (185 BCE) - historically impossible.
Option 3: (D), (C), (A), (B) -> Places Arab conquest (712 CE) before Gupta rule (320 CE) and Pallava rise - incorrect order.
Option 4: (C), (B), (D), (A) -> Completely inverted chronology placing medieval events before ancient ones - incorrect.
Hence, Option 1: (D), (A), (B), (C) -> The Mauryan empire ended around 185 BCE, followed by the beginning of Gupta rule in 320 CE, then the rise of the Pallavas in the 6th century CE, and finally the Arab conquest of Sind in 712 CE, making this the correct chronological sequence from ancient to medieval India -> correct
