Cerebral hemispheres are the centres of:

Options

A. taste
B. smell
C. balance
D. thinking

Explanation

### Step-by-Step Solution:

1. **Identify the Structure**: The cerebral hemispheres are the two halves of the brain, which play a crucial role in various functions.

2. **Understand the Lobes**: The cerebral hemispheres consist of four main lobes:
- **Frontal Lobe**: Responsible for higher cognitive functions such as thinking, decision-making, and problem-solving.
- **Parietal Lobe**: Involved in processing sensory information, including taste.
- **Temporal Lobe**: Associated with processing auditory information and is also linked to the sense of smell.
- **Occipital Lobe**: Primarily responsible for vision.

3. **Function Allocation**: Each lobe has specific functions:
- **Frontal Lobe**: Thinking
- **Parietal Lobe**: Taste
- **Temporal Lobe**: Smell
- **Occipital Lobe**: Vision

4. **Exclusion of Other Functions**: It is important to note that balance is not controlled by the cerebral hemispheres but rather by the cerebellum, which is a separate part of the brain.

5. **Conclusion**: Therefore, the cerebral hemispheres are the centers for taste, smell, and thinking, while balance is managed by the cerebellum.
