\nLet’s establish the approximate dates for each event:
\n1. Invasion of Alexander: 326 BCE.
\n2. Indo-Greek Rule in the North-West: Started around the late 3rd\/early 2nd century BCE (after the decline of the Mauryas) and lasted until the 1st century BCE\/1st century CE.
\n3. Accession of Kanishka: Debated, but commonly placed around 78 CE (start of Shaka Era) or mid-2nd century CE. Kanishka was a Kushan ruler.
\n4. Accession of Chandragupta Maurya: Founded the Mauryan Empire around 321 BCE, shortly after Alexander’s withdrawal from parts of India.<\/p>\nThe chronological order is: Alexander’s invasion (326 BCE), followed immediately by Chandragupta Maurya’s rise to power (c. 321 BCE), then the establishment of Indo-Greek rule after the Mauryan decline (post 185 BCE), and finally the accession of Kanishka much later (1st\/2nd century CE).
\nThus, the correct order is 1 – 4 – 2 – 3.
