To answer the question, "Which part of the brain is linked to memory, intelligence, and learning power?", we will analyze each of the given options step by step.
### Step 1: Analyze the First Option - Medulla
- The first option is "Medulla."
- The medulla oblongata is a part of the brainstem that controls autonomic functions such as breathing, heart rate, and blood pressure.
- It does not play a significant role in memory, intelligence, or learning.
**Hint:** Remember that the medulla is primarily involved in regulating vital functions, not cognitive processes.
### Step 2: Analyze the Second Option - Cerebrum
- The second option is "Cerebrum."
- The cerebrum is the largest part of the brain and is responsible for higher brain functions, including memory, intelligence, and learning.
- It is divided into two hemispheres and contains areas that are specifically involved in processing information related to these cognitive functions.
**Hint:** The cerebrum is where most of our complex thought processes occur, making it crucial for memory and learning.
### Step 3: Analyze the Third Option - Cerebellum
- The third option is "Cerebellum."
- The cerebellum is located at the back of the brain and is primarily responsible for coordinating muscle movements, balance, and posture.
- It does not have a direct role in memory or intelligence.
**Hint:** Think of the cerebellum as the part of the brain that helps with physical coordination rather than cognitive abilities.
### Step 4: Analyze the Fourth Option - Hypothalamus
- The fourth option is "Hypothalamus."
- The hypothalamus is involved in regulating various autonomic functions and homeostasis, such as temperature control, hunger, and hormonal release.
- While it plays a role in emotional responses, it is not directly linked to memory or intelligence.
**Hint:** The hypothalamus is more about regulating bodily functions than cognitive processes.
### Conclusion
After analyzing all the options, the part of the brain that is linked to memory, intelligence, and learning power is the **Cerebrum** (Option 2).
**Final Answer:** Cerebrum
