Heya!
ANSWER:
Blood circulation improves the body functions and stabilizes it
If I'm understanding you correctly (sorry, I'm new at this) It sounds like you are describing an accident that either didn't actually happen, or was minor compared to what could have happened. I would call this a "near miss" or "close call"
Explanation:
For example: I had a near miss today when a dog ran out in front of me.
Or: He had a close call when his foot almost slipped over the edge of the cliff.
The answer would be C.) Fighting for a noble cause.
Thank you :)
