Which of the following represents the year in which Alexander invaded India ........

Explanation:

The Indian campaign of Alexander the Great began in 326 BC. After conquering the Achaemenid Empire of Persia, the Macedonian king (and now the great king of the Persian Empire), Alexander, launched a campaign into the Indian subcontinent in present-day Pakistan, part of which formed the easternmost territories of the Achaememid Empire following the Achaemenid conquest of the Indus Valley (6th century BC). The rationale for this campaign is usually said to be Alexander's desire to conquer the entire known world, which the Greeks thought ended in India.
