The correct answer is (a) Bahraich.
Syed Salar Fair is a Muslim fair held in Bahraich, India, in the month of Rabi-ul-Awwal. It is held in commemoration of the death of Syed Salar Masud Ghazi, a 10th-century Muslim saint. The fair attracts millions of pilgrims from all over India and Pakistan.
The fair is a major cultural event, and features a variety of activities, including religious ceremonies, music, dance, and food stalls. It is also a major economic event, and generates millions of rupees in revenue for the local economy.
The fair is held over a period of 10 days, and begins with a procession of pilgrims from the shrine of Syed Salar Masud Ghazi to the fairground. The procession is led by a group of musicians, who play traditional music on drums and trumpets.
The fairground is a large area, and is divided into different sections. The main section is the religious area, where pilgrims can offer prayers and make offerings to Syed Salar Masud Ghazi. There is also a food court, where pilgrims can buy traditional Indian food.
The fair is a major tourist attraction, and is a popular destination for both Indian and foreign tourists. It is a time for people to come together and celebrate their culture and religion.
The other options are incorrect because they are not the places where Syed Salar Fair is held.
