When facing the repression, the minorities could choose to submit by letting the repressor walk over them, they could choose to create a violent ressistence by forming a rebellion group to override the current government, or they can withdraw from the repression by forming their independent nation.
Based on the given options, I can say that what a minority group may do in response to repression are withdrawing from the repression, submitting to repression, and violently resisting the repression. The answer for this would be all of the above. It would be option C. Hope this helps.
