Answer:
A
Explanation:
a martyr dies for a cause. these martyrs "died" or sacrificed themselves for loving the author/speaker
B would be incorrect because "So did two others from our youth group." is an incomplete sentence.
THe second sentence is using present participle because you said " I promise" not "promised". Saying promise is when you are saying it at the time and saying promised means you've already said it. Like with how you said "kissed" instead of "kiss" in the first sentence.
