Match the column I with column II and choose the correct combination from the options given.
`{:(" Column I",," Column II"),("(Component)",,"(% of the total cellular mass)"),(A."""Ions ",,(i)"1"),(B."" "Lipids",,(ii)"2"),(C."" "Carbohydrates",,(iii)"3"),(D."""Nucleic acids",,(iv)"5-7"),(E."""Proteins",,(v) "10-15"):}`

Options

A. `A-(i), B-(ii), C-(iii), D-(iv), E-(v)`
B. `A-(ii), B-(iii), C-(i), D-(v), E-(iv)`
C. `A-(iii), B-(i), C-(ii), D-(iv), E-(v)`
D. `A-(iv), B-(ii), C-(iii), D-(v), E-(i)`

Answer

To solve the problem of matching the components from Column I with their respective percentages in Column II, we will analyze each component and determine its approximate percentage of total cellular mass based on biological knowledge.

### Step-by-Step Solution:

1. **Identify the components in Column I:**
- A. Ions
- B. Lipids
- C. Carbohydrates
- D. Nucleic acids
- E. Proteins

2. **Determine the approximate percentage of total cellular mass for each component:**
- **A. Ions:** Ions are present in very small amounts in cells, typically around **1%** of the total cellular mass.
- **B. Lipids:** Lipids, which include fats and phospholipids, are also present in small amounts, generally around **2%** of the total cellular mass.
- **C. Carbohydrates:** Carbohydrates, such as glucose and glycogen, are present in moderate amounts, usually about **3%** of the total cellular mass.
- **D. Nucleic acids:** Nucleic acids (DNA and RNA) are crucial for genetic information and are present in a larger proportion than carbohydrates, typically around **5-7%** of the total cellular mass.
- **E. Proteins:** Proteins are essential for various cellular functions and are the most abundant biomolecules after water, usually comprising about **10-15%** of the total cellular mass.

3. **Match the components with their respective percentages:**
- A (Ions) matches with (i) 1%
- B (Lipids) matches with (ii) 2%
- C (Carbohydrates) matches with (iii) 3%
- D (Nucleic acids) matches with (iv) 5-7%
- E (Proteins) matches with (v) 10-15%

4. **Final Matching:**
- A → i (1)
- B → ii (2)
- C → iii (3)
- D → iv (5-7)
- E → v (10-15)

5. **Select the correct combination from the options given:**
- The correct combination is: A with 1, B with 2, C with 3, D with 4, E with 5.

### Conclusion:
The correct answer is the first option: A → 1, B → 2, C → 3, D → 4, E → 5.
