The last ruler of the Nanda dynasty, who was overthrown by Chandragupta Maurya, was

The correct answer is C, Dhana Nanda. He was the last of the Nanda kings of Magadha and ruled when Alexander invaded the Punjab; Greek writers describe the vast army of the Gangaridai and Prasii that waited beyond the Beas. His heavy taxation and unpopularity gave Chandragupta Maurya, guided by Chanakya, the opening to overthrow him and found the Mauryan empire at Pataliputra.

Option A, Kalashoka, belonged to the earlier Shishunaga dynasty and is remembered for the Second Buddhist Council at Vaishali. Option B, Udayin, belonged to the Haryanka dynasty and founded Pataliputra. Option D, Bindusara, came after the change of dynasty altogether: he was the son of Chandragupta Maurya and the father of Ashoka, so he cannot be a Nanda. Fix the sequence Haryanka, Shishunaga, Nanda, Maurya and the last name in each line. Note also that Dhana Nanda is remembered chiefly through the accounts of Alexander's companions and through later Sanskrit drama, so the same name may be asked as the contemporary of Alexander rather than as the last Nanda.
