The correct answer is option 1: San Francisco. The headquarters of the Ghadar Movement/Party were located in San Francisco.
The Ghadar Movement/Party was a political and revolutionary organization founded by Indian immigrants in the early 20th century. It aimed to overthrow British colonial rule in India and establish a free and independent nation.
San Francisco was chosen as the headquarters of the Ghadar Movement due to its large Indian immigrant population and its proximity to the West Coast ports, which facilitated communication and transportation with India. The city also provided a supportive environment for political activism and had several Indian-run businesses and organizations.
Stanford University, mentioned in option 2, is not the correct answer. While Stanford University is located in California like San Francisco, it does not have any connection to the Ghadar Movement.
Portland, mentioned in option 3, and Florida, mentioned in option 4, are also incorrect. These locations do not have any historical association with the Ghadar Movement.
In conclusion, the headquarters of the Ghadar Movement/Party were located in San Francisco.
