Match the columns.
`{:("Column A","Column B"),(1."Cochlea",A."Bipolar cells"),(2."Retina",B."Tectorial membrane"),(3."Forebrain",C."Corpus callosum"),(,D."White matter"),(,E."Hair cells"):}`

Options

A. 1 – B, E, 2–A, D, 3 – C
B. 1 – B 2 – E, A, 3 – C, D
C. 1 – B E, 2– C, D, 3– A
D. 1 – B E, 2 – A , 3– C, D

Answer

To solve the matching question, we will analyze each item in Column A and find its corresponding match in Column B.

### Step-by-Step Solution:

1. **Cochlea**:
- The cochlea is part of the inner ear and is crucial for hearing. It contains hair cells that convert sound vibrations into neural signals.
- The tectorial membrane is associated with the cochlea and lies over the hair cells.
- Therefore, cochlea matches with **B (Tectorial membrane)** and **E (Hair cells)**.

2. **Retina**:
- The retina is the light-sensitive layer at the back of the eye and contains photoreceptor cells.
- Bipolar cells are a type of neuron found in the retina that transmit signals from photoreceptors to ganglion cells.
- Hence, retina matches with **A (Bipolar cells)**.

3. **Forebrain**:
- The forebrain is the largest part of the brain and includes structures such as the corpus callosum and white matter.
- The corpus callosum facilitates communication between the left and right hemispheres of the brain, while white matter consists of myelinated axons that connect different brain regions.
- Therefore, forebrain matches with **C (Corpus callosum)** and **D (White matter)**.

### Final Matches:
- 1. Cochlea → B (Tectorial membrane), E (Hair cells)
- 2. Retina → A (Bipolar cells)
- 3. Forebrain → C (Corpus callosum), D (White matter)

### Conclusion:
The most appropriate option that summarizes these matches is:
- 1 → B, E
- 2 → A
- 3 → C, D

Thus, the correct answer is **Option D**.
