The correct answer is B. Kullu.
The Kullu Dussehra is a 10-day festival celebrated in the Kullu Valley in Himachal Pradesh, India. It is one of the most important festivals in the state and is a major tourist attraction. The festival is held in the month of October and marks the victory of good over evil.
The festival begins with the arrival of the royal family of Kullu at the Dussehra ground. The royal family is then taken in a procession to the temple of Raghunathji, the main deity of Kullu. The procession is accompanied by music, dancing, and singing.
The main event of the festival is the Dussehra battle. This is a reenactment of the battle between Rama and Ravana, the two main characters in the Ramayana. The battle is fought between two groups of people, one representing Rama and the other representing Ravana. The battle is a spectacular event and is a major attraction for tourists.
The festival ends with the burning of an effigy of Ravana. This marks the victory of good over evil.
