Match the enzymes with their respective substrates and choose the right one among options given.
`{:("Column I","Column II"),("Lipase",(i)"Dipeptides"),("Nuclease",(ii)"Fats"),("Carboxypeptidase",(iii)"Nucleic acids"),("Cipeptidases",(iv)"Proteins, peptones and proteoses"):}`

Options

A. a) ii,iii,I,iv
B. b) iii,iv,ii,i
C. c) iii,I,iv,ii
D. d) ii,iii,iv,i

Answer

To solve the question of matching enzymes with their respective substrates, we will analyze each enzyme in Column I and identify the correct substrate from Column II.

### Step-by-Step Solution:

1. **Identify the first enzyme: Lipase**
- **Function**: Lipase is an enzyme that breaks down fats (lipids).
- **Match**: Lipase → (ii) Fats

2. **Identify the second enzyme: Nuclease**
- **Function**: Nuclease is an enzyme that breaks down nucleic acids (DNA and RNA).
- **Match**: Nuclease → (iii) Nucleic acids

3. **Identify the third enzyme: Carboxypeptidase**
- **Function**: Carboxypeptidase is an enzyme that acts on proteins, specifically breaking down peptides into amino acids.
- **Match**: Carboxypeptidase → (iv) Proteins, peptones, and proteoses

4. **Identify the fourth enzyme: Dipeptidases**
- **Function**: Dipeptidases are enzymes that break down dipeptides into amino acids.
- **Match**: Dipeptidases → (i) Dipeptides

### Final Matching:
- Lipase → (ii) Fats
- Nuclease → (iii) Nucleic acids
- Carboxypeptidase → (iv) Proteins, peptones, and proteoses
- Dipeptidases → (i) Dipeptides

### Sequence of Matches:
- Lipase: 2
- Nuclease: 3
- Carboxypeptidase: 4
- Dipeptidases: 1

Thus, the final sequence is 2, 3, 4, 1.

### Correct Option:
The correct option is **D: 2, 3, 4, 1**.
