None of the options you've provided directly suggest a strategy for resolving conflict with violence, as addressing conflict through violence is generally not advisable or effective. However, if you're looking for a strategy that promotes peaceful resolution of conflict, option A ("Take time out to think before responding") would be the most appropriate. Taking a step back allows individuals to cool down and consider their options thoughtfully, which can help prevent escalation into violence.
The other options listed—building empathy, seeking feedback through social media, and trying to get others to agree—do not inherently promote violence but they also do not resolve conflict in a constructive way. Instead, fostering understanding and communication is more beneficial in resolving conflicts peacefully.
