Explanation:

This question asks to identify which among the given options is not a traditional folk song genre originating from or primarily associated with Uttar Pradesh. - **Option (A) Birha:** Birha is indeed a very popular and traditional folk song genre of Uttar Pradesh, particularly prevalent in the Bhojpuri-speaking regions of the state. These songs often narrate tales of separation, heroism, or social commentary, typically performed by male singers. Therefore, this option is a folk song of Uttar Pradesh. - **Option (B) Dhola Maru:** This is the correct answer as it is *not* a folk song of Uttar Pradesh. Dhola Maru is a renowned romantic folk ballad and song tradition that primarily originates from and is popular in Rajasthan. It recounts the legendary love story of Prince Dhola and Princess Maru. Therefore, this option is not a folk song of Uttar Pradesh. - **Option (C) Kajari:** Kajari is a significant and widely recognized folk song genre of Uttar Pradesh, especially popular during the monsoon season. These songs are predominantly sung by women, expressing themes of longing, love, and the beauty of nature during the rainy months. Therefore, this option is a folk song of Uttar Pradesh. - **Option (D) Rasia:** Rasia is another prominent folk song form of Uttar Pradesh, particularly associated with the Braj region (which includes Mathura and Vrindavan). Rasia songs are often performed during festivals like Holi and depict the playful and devotional aspects of Lord Krishna's life. Therefore, this option is a folk song of Uttar Pradesh.\nHence, Dhola Maru is the only option that is not a folk song of Uttar Pradesh; it belongs to Rajasthan.
