B) second-degree block type I.
C) second-degree block type II.
D) third-degree block.

Third-degree block, also known as complete heart block, is characterized by the complete dissociation of the atria and ventricles. The P waves and QRS complexes occur independently of each other, with no correlation between them. This results in a slow, ventricular escape rhythm that is independent of the atrial rate. The other options refer to various degrees of AV block but still have some correlation between the P waves and QRS complexes.
