Correct Option: B

A dispute between the textile mill-owners and the labourers at Ahmedabad arose in 1918, about the grant of bonus and dearness allowance. The labourers wanted 50% increase allowance due to steep rise in prices. The mill-owners were ready to give only 20% increase. Gandhi was approached to find a solution. He persuaded both the parties to agree to arbitration. But after a few days, some misunderstanding led to a strike. The mill-owners seized the opportunity and declared lock-out. Gandhi studied the case. He thought that 35% increase would be reasonable. He advised the labourers to demand the same. Regular strike began on the 26th February 1918. This campaign attracted less publicity because it was directed against Indian employers, not government officials. During this episode, the mill-owners was led by Shri Ambalal Sarabhai. His sister Ansuyaben led the labourers.
