C. creates the most urgent mood.
Comparing to the others, C. has the fastest pacing, as you can see the sentence are cut short. Sentences like “No! No time.” and “threw open the door” also creates an urgent feeling.
Meanwhile for A., the pacing is slower with the use of inversion. It is unlikely for the reader to sense the urgency from such slow pacing.
For B., the pacing is more urgent, but the continuous actions that are narrative did not creat a strong sense of urgency.
For D., although the message of rushing against time is implied, the pacing in sentense is relatively weak as you can see from the long sentense.
Hope it helps!
