The correct answer is: Zaverchand Meghani.
Manvini Bhavai is a famous Gujarati play written by Zaverchand Meghani in 1887. It is a social satire that criticizes the hypocrisy and superstitions of the Gujarati society of the time. The play is set in the village of Bhavnagar and tells the story of a young man named Manvini who is seduced by a beautiful woman named Bhavai. Manvini is eventually abandoned by Bhavai and is left to face the consequences of his actions.
