Which of the following states in India does not have a bicameral legislature?

A bicameral legislature means a legislature with two houses — the Legislative Assembly (Vidhan Sabha) and the Legislative Council (Vidhan Parishad). Only a few Indian states have bicameral legislatures such as Bihar, Maharashtra, Uttar Pradesh, Telangana, Karnataka, and Andhra Pradesh. Madhya Pradesh has only a unicameral legislature (Vidhan Sabha), hence the correct answer.
