Bindusara asked Antiochus I to send three things — sweet wine

Correct answer: A philosopher or sophist. Classical tradition says Bindusara requested sweet wine, dried figs and a philosopher or sophist from Antiochus I. The first two could be supplied, but the sale of a philosopher was said to be contrary to Greek custom or law. The distinctive item in the anecdote is a philosopher or sophist, not a physician, general, sculptor or other professional substituted by distractors. The answer should be chosen from the specific evidence asked in the question, not from a broad association with the Mauryan period.
