Correct answer
Explanation
The Saka era began in 78 AD with the accession of Kanishka, the great Kushan ruler. This calendar system was widely used in ancient India and continues in some contexts today. Ashoka (3rd century BC) and Chandragupta II (4th century AD) lived in different periods. Harsha came much later (7th century AD). Kanishka's reign marked the beginning of this important chronological marker in Indian history.
