The correct answer is (a) Gurupatwant Singh Pannu.
Gurupatwant Singh Pannu is a Sikh separatist leader who is the chief of the banned organization Sikhs for Justice (SFJ). He is wanted by the Indian government for his alleged involvement in the 2016 Pathankot attack.
In 2020, Pannu was arrested in Canada on charges of extradition to India. However, he was released on bail in 2021.
In 2022, Pannu was accused of inciting violence in India after he called for a “Khalistan referendum”. This led to a deterioration in Indo-Canadian relations.
The other options are incorrect because:
(b) Lakhbir Landa is a Canadian Sikh who is wanted by the Indian government for his alleged involvement in the 2015 Gurdaspur attack.
(c) Harvinder Rinda is a Pakistani-based Sikh militant who is wanted by the Indian government for his alleged involvement in several terrorist attacks in India.
(d) Hardeep Singh Nijjar is a Canadian Sikh who is a former member of the SFJ. He was expelled from the SFJ in 2017 after he criticized Pannu’s leadership.
