Corpora striata is
(a) Roof of lateral ventricle
(b) Floor of lateral ventricle
(c) Lateral walls of lateral ventricle
(d) None of these

Options

A. Roof of lateral ventricle
B. Floor of latral ventricle
C. Lateral walls of lateral ventricle
D. None of these

Answer

To solve the question regarding the anatomical location of the corpora striata, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure in Question**: The question asks about the corpora striata, which is a part of the brain. It is important to know its location in relation to the lateral ventricle.

2. **Identify the Components of the Lateral Ventricle**: The lateral ventricle has three main components:
- A roof
- A floor
- Lateral walls

3. **Determine the Composition of Each Component**:
- The **roof** of the lateral ventricle is formed by the **corpus callosum**.
- The **floor** of the lateral ventricle is formed by the **corpora striata**.
- The **median wall** is formed by the **septum pellucidum**.

4. **Analyze the Options Given**:
- (a) Roof of lateral ventricle - Incorrect, as the roof is made by the corpus callosum.
- (b) Floor of lateral ventricle - Correct, as the floor is made by the corpora striata.
- (c) Lateral walls of lateral ventricle - Incorrect, as the lateral walls are not made by the corpora striata.
- (d) None of these - Incorrect, as we have identified the correct option.

5. **Select the Correct Answer**: Based on the analysis, the correct answer is (b) Floor of lateral ventricle.

### Final Answer:
(b) Floor of lateral ventricle
