Moa is explained by Bebix or Apx85 on another thread, but i'll post here:

Atrophine will cause stimulation of M receptors leading to increased heart rate, but overall decrease in MBP.

None of the other choices do that, except maybe digoxin, which isn't the best initial therapy for an unknown condition.

Good morning

In the emergent setting, atropine may be effective by reversing the decrease in AV nodal conduction induced by vagal tone. A favorable response to atropine suggests that AV block is due to abnormal conduction in the AV node, since the more distal conducting system is not as sensitive to vagal activity.
