Explanation:

Folk art forms are an integral part of India's diverse cultural heritage, often reflecting regional traditions, beliefs, and daily life. * **Correct Option (A) Rajasthan:** "Madana" (or Mandana) is a traditional folk art form of wall and floor painting predominantly practiced in the state of Rajasthan, India. It is typically created by women using white chalk solution and red ochre on mud walls and floors, often depicting geometric patterns, deities, and natural motifs. These intricate designs are made on auspicious occasions, festivals, and religious ceremonies, believed to bring prosperity and ward off evil. * **Incorrect Option (B) Gujarat:** Gujarat is known for its vibrant folk arts like Warli painting (shared with Maharashtra), Pithora painting, and Rogan art, but Mandana is not its primary folk art form. * **Incorrect Option (C) Maharashtra:** Maharashtra is famous for Warli painting, a tribal art form characterized by simple linear figures, and other regional art styles. However, Mandana is not native to Maharashtra. * **Incorrect Option (D) Bihar:** Bihar is renowned for Madhubani painting (also known as Mithila art), a distinct and ancient style of folk painting characterized by its intricate patterns and vibrant colors, which is different from Mandana.
