**Core Concept**
The **conduction system of the heart** plays a crucial role in regulating the heartbeat. The **purkinje fibers** are a part of this system, responsible for rapidly transmitting signals to the ventricles. The correct order of activation after stimulation of purkinje fibers is related to the **electrophysiology of the heart**.

**Why the Correct Answer is Right**
After stimulation of **purkinje fibers**, the signal is transmitted to the **ventricular muscle cells**, leading to **depolarization** and **contraction**. The correct order of activation is related to the **anatomical structure** and **electrical properties** of the heart.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately reflect the order of activation after stimulation of purkinje fibers.
**Option B:** This option is also incorrect as it does not follow the correct sequence of electrical activation in the heart.
**Option D:** This option is incorrect because it misrepresents the normal pathway of electrical conduction in the heart.

**Clinical Pearl / High-Yield Fact**
The correct order of activation is essential for understanding **arrhythmias** and **conduction disorders**. Remembering the sequence can help in diagnosing and managing **cardiac conditions**.
