The correct options are
A The Morcha of Jaito was organised in response to the British policemen disrupting peaceful protests at Gangsar Gurdwara.
B Akali Dal sent a Jatha of 25 Sikhs for six months regardless of the brutal treatment by the British.
C The first Jatha of 500 Sikhs travelled to Jaito and inspired people from villages along the way to join the March.
The Akalis sent a Jatha of 25 Sikhs to reclaim Gangsar Gurudwara, but they were arrested. They kept sending Jathas of 25 Sikhs for six months regardless of the police high-handedness and maltreatment meted out to them. The Shiromani Committee after a point decided to bump the numbers up to 500 per Jatha. The first Jatha of 500 people garnered the support of the villages it passed through, and the Jatha had grown into a thousand-strong march when they entered the state of Nabha. The Akali Jatha was a peaceful demonstration that didn't become violent despite the maltreatment received by the British government.
