Options

A. i - Medulla, ii - cerebellum
B. i-cerebellum, ii- cerebrum dows
C. i- cerebrum, ii - hypothalamus
D. i - hypothalamus, ii - modullaens

Answer

**Step-by-Step Solution:**

1. **Identify the Parts of the Brain:**
- We need to determine which part of the brain is responsible for involuntary actions and which part is responsible for voluntary actions.

2. **Involuntary Actions:**
- The part of the brain that controls involuntary actions (such as heartbeat, digestion, and respiration) is the **medulla oblongata**. This region is crucial for regulating essential life functions that occur without conscious thought.

3. **Voluntary Actions:**
- The part of the brain that controls voluntary actions (like movement, coordination, and balance) is the **cerebellum**. This area is responsible for fine-tuning motor activity and ensuring smooth and coordinated movements.

4. **Formulate the Complete Statement:**
- Based on the information gathered, we can complete the statement as follows:
- "The medulla oblongata is a part of the brain which controls all the involuntary actions of the body, while the cerebellum is a part of the brain which controls all the voluntary actions of the body."

5. **Final Answer:**
- i) Medulla oblongata
- ii) Cerebellum
