Answer to Question 1

B
Most of the bundle branch tissue is supplied by a branch of the left coronary artery.

Answer to Question 2

C
In third-degree atrioventricular (AV) block, both the atrial and ventricular rhythms are regular, but the atria and ventricles beat independently; therefore the P waves that are present are unrelated to the QRS complexes (i.e., AV dissociation exists).
