Q. Who of the following was a contemporary of Alexander, the Great?
(a) Bimbisara
(b) Chandragupta Maurya
(c) Ashoka
(d) Pushyamitra Sunga
Ans: (b) Chandragupta Maurya
Explanation: The correct answer is (b) Chandragupta Maurya. Chandragupta Maurya, the founder of the Maurya Empire, was a contemporary of Alexander the Great. While Alexander was busy conquering Persia and the eastern regions, Chandragupta Maurya was establishing his own empire in the Indian subcontinent. Though there is no direct historical evidence of a direct encounter between Alexander and Chandragupta, their timelines overlap, and they were both significant figures in their respective regions during the same period.
