Read the following matches carefully:
(i) Corpus callosum: Connects both right and left cerebellar hemispheres.
(ii) Limbic system: Regulation of sexual behaviour and emotional with the hypothalamus.
(iii) Association areas: Responsible for intercessory associations, memory and communication.
(iv) Medulla oblongata: Controls motivation and urge for eating and drinking.
How many of the above matches is / are incorrect ?

Options

A. Three
B. Four
C. One
D. Tow

Answer

To determine how many of the given matches are incorrect, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze Statement (i)**:
- **Statement**: "Corpus callosum: Connects both right and left cerebellar hemispheres."
- **Analysis**: The corpus callosum actually connects the right and left **cerebral** hemispheres, not the cerebellar hemispheres. Therefore, this statement is **incorrect**.

2. **Analyze Statement (ii)**:
- **Statement**: "Limbic system: Regulation of sexual behaviour and emotional with the hypothalamus."
- **Analysis**: The limbic system does play a role in regulating emotions and sexual behavior, often in conjunction with the hypothalamus. This statement is **correct**.

3. **Analyze Statement (iii)**:
- **Statement**: "Association areas: Responsible for intercessory associations, memory and communication."
- **Analysis**: Association areas are indeed responsible for integrating sensory information, memory, and communication. This statement is **correct**.

4. **Analyze Statement (iv)**:
- **Statement**: "Medulla oblongata: Controls motivation and urge for eating and drinking."
- **Analysis**: The medulla oblongata is responsible for involuntary functions like breathing, heart rate, and reflexes, but it does not control motivation or the urge for eating and drinking; that function is primarily associated with the hypothalamus. Therefore, this statement is **incorrect**.

### Summary of Findings:
- **Incorrect Statements**:
- Statement (i) about the corpus callosum.
- Statement (iv) about the medulla oblongata.

Thus, **2 statements are incorrect**.

### Final Answer:
**2 statements are incorrect.**
