Final answer:
The correct order of these Indian emperors is Ashoka, followed by Chandragupta I, then Samudragupta, and finally Chandragupta II.
Step-by-step explanation:
To determine the correct order of these Indian emperors, we need to look at historical timelines. Starting with Ashoka the Great, he was an emperor of the Maurya Dynasty who reigned from approximately 268 to 232 BCE. Following him, Chandragupta I founded the Gupta Dynasty around 320 CE. His successor and son, Samudragupta, continued the expansion and consolidation of the Gupta Empire. After Samudragupta, Chandragupta II, his son, took power and further strengthened the empire. Therefore, the correct order is Ashoka, Chandragupta I, Samudragupta, and then Chandragupta II.
