To determine the correct options regarding the statements about the human brain's division into forebrain, midbrain, and hindbrain, we will analyze each statement step by step.
### Step-by-Step Solution:
1. **Statement i**: "The cerebral cortex contains motor areas, sensory areas and large association areas."
- **Evaluation**: This statement is **correct**. The cerebral cortex indeed has designated areas for motor functions, sensory processing, and large association areas that integrate information.
2. **Statement ii**: "Association areas are clearly sensory and motor in function and it related with complex functions like inter sensory association, memory and communication."
- **Evaluation**: This statement is **incorrect**. Association areas are not strictly sensory or motor; they are involved in higher-order functions such as memory and communication.
3. **Statement iii**: "Thalamus is a major coordinating centre for sensory and motor signalling."
- **Evaluation**: This statement is **correct**. The thalamus acts as a relay station for sensory and motor signals.
4. **Statement iv**: "The hypothalamus contains a number of centres which control body temperature, urge for eating and drinking."
- **Evaluation**: This statement is **correct**. The hypothalamus regulates various autonomic functions, including temperature control and hunger.
5. **Statement v**: "The inner parts of cerebral hemispheres, amygdala, hippocampus, etc., form a complex structure called the limbic lobe or limbic system."
- **Evaluation**: This statement is **correct**. The limbic system includes structures like the amygdala and hippocampus, which are involved in emotion and memory.
6. **Statement vi**: "Along with the hypothalamus, limbic system is involved in the regulation of sexual behaviour, expression of emotional reactions and motivation."
- **Evaluation**: This statement is **correct**. Both the hypothalamus and limbic system play roles in emotional responses and sexual behavior.
7. **Statement vii**: "A canal called the cerebral aqueduct passes through the hindbrain."
- **Evaluation**: This statement is **incorrect**. The cerebral aqueduct is located in the midbrain, not the hindbrain.
8. **Statement viii**: "The medulla contains centres which control respiration, cardiovascular reflexes and gastric secretions."
- **Evaluation**: This statement is **correct**. The medulla oblongata is responsible for autonomic functions such as breathing and heart rate.
### Summary of Evaluations:
- Correct Statements: i, iii, iv, v, vi, viii
- Incorrect Statements: ii, vii
### Correct Option:
The correct option that contains only correct statements is:
- **Option 4**: i, iii, iv, v, vi, viii
