Explanation:

• The peasants of the Champaran and other areas of North Bihar were growing the Indigo under the tinakathia system. Under the tinakathia system, the peasants were bound to plant 3 out of 20 parts of his land with indigo for his landlord. 
• This means that out of 20 khatas which make an acre, they had to dedicate 3 khatas for indigo plantation. This was the root cause of the trouble. They had to lease this part in the return to the advance at the beginning of each cultivation season.
• The price was too less and was fixed on the area cultivated rather than the crop produced. They were actually being cheated by the English planters. The planters had agreed to the peasants to relive them from the lease contracts but demanded heavy compensations which they were not able to pay. 
• One local peasant leader Rajkumar Shukla had invited Mahatma Gandhi to visit Champaran. Gandhi Ji arrived in Champaran but was later ordered by the District magistrate of Champaran WB Heycock to leave the district. Gandhi Ji refused and persisted. He decided to commit Satyagraha. He proceeded towards the Champaran. 
• The commissioner of tirhut division ordered Gandhi’s arrest but Government of India cancelled the arrest because it did want to make him a hero.

Hence only statement 1st is correct.
