Identify the parts of the forebrain among the following

Options

A. Cerebrum
B. Diencephalon
C. Corpus collasum
D. Both (a) and (b)

Explanation

### Step-by-Step Solution:

1. **Understanding the Forebrain**: The forebrain, also known as the prosencephalon, is a major part of the brain that includes various structures responsible for complex functions. It consists of two main parts: the telencephalon and the diencephalon.

2. **Identifying the Components of the Forebrain**:
- **Telencephalon**: This part includes the cerebral hemispheres, which are involved in higher brain functions such as thought, action, and sensory processing.
- **Diencephalon**: This includes structures such as the thalamus, hypothalamus, epithalamus, and subthalamus, which are crucial for sensory information processing and regulation of various bodily functions.

3. **Analyzing the Options**:
- **Option A: Saribram**: This is a correct option as it refers to the cerebrum, which is part of the telencephalon.
- **Option B: Diencephalon**: This is also a correct option as it is explicitly mentioned as part of the forebrain.
- **Option C: Corpus Callosum**: This is incorrect because the corpus callosum is a structure that connects the two cerebral hemispheres but is not classified as part of the forebrain itself.
- **Option D: Both A and B**: This option is correct since it includes both the cerebrum and the diencephalon, which are parts of the forebrain.

4. **Conclusion**: The correct answer is option D, which includes both A (Saribram) and B (Diencephalon) as parts of the forebrain.
