The correct options are
A Arrested Gandhi
C Arrested the protestors
D Declared Martial Law
Fearing that Gandhiji's Civil Disobedience will inspire more people to protest for independence, the British arrested Gandhiji. They also arrested protestors in a move to contain the movement and declared Martial law in Solapur. Many activists were arrested and executed for this. But this move backfired because these arrests incited protests all over the country.
