When There Are More P Waves Than QRS Complexes It

When there are more P waves than QRS complexes it indicates that:

A) impulses are arising from the lower-right atrium near the AV node or in the left atrium.
B) the atria are firing so fast that not all the impulses can pass through the AV node and some are blocked.
C) impulses are initiated in the SA node or other ectopic sites in the atria but are blocked and do not reach the ventricles.
D) impulses are arising from many different locations in the atria.
