Select the correct match the following.
`{:("Column I","Column II"),("I Phosphorus","a Nitrogenase"),("ii Magnesium","b Water splitting"),("iii Sulphur ","c Nucleic acids "),("iv Chlorine ","Thiamine"),(,"Ribosome structure"):}`

Options

A. i- e , ii - a , iii - c, iv - d
B. i- c , ii - e , iii - d, iv - b
C. i- b , ii - c , iii - a , iv - e
D. i- c , ii - a , iii - d , iv - b

Answer

To solve the question of matching elements from Column I with their corresponding functions or associations in Column II, we will analyze each pairing step by step.

### Step-by-Step Solution:

1. **Phosphorus**:
- Phosphorus is an essential element that is a key component of nucleic acids (DNA and RNA).
- Therefore, we match **Phosphorus (I)** with **Nucleic acids (c)**.

2. **Magnesium**:
- Magnesium is crucial for the structure and function of ribosomes, as it helps in the association of ribosomal subunits.
- Thus, we match **Magnesium (ii)** with **Ribosome structure (E)**.

3. **Sulfur**:
- Sulfur is an important element in the structure of certain amino acids and is also found in some vitamins. However, it is not directly related to Thiamine, which is a vitamin but not a sulfur compound.
- The correct match for Sulfur is not provided in the options, but it is often associated with various biological functions, including being part of certain amino acids.
- For the sake of this question, we can tentatively match **Sulfur (iii)** with **Thiamine (D)**, although this is a less direct association.

4. **Chlorine**:
- Chlorine plays a role in the process of water splitting during photosynthesis, where it helps in the release of oxygen from water.
- Therefore, we match **Chlorine (iv)** with **Water splitting (b)**.

### Summary of Matches:
- I (Phosphorus) → c (Nucleic acids)
- ii (Magnesium) → E (Ribosome structure)
- iii (Sulfur) → D (Thiamine)
- iv (Chlorine) → b (Water splitting)

### Final Answer:
The correct matches are:
- I → c
- ii → E
- iii → D
- iv → b
