Match the column I and column II and mark the appropriate choice.
`{:("(A) Diastase"," (i) Proteins "rarr. "peptones"),("(B) Pepsin ","(ii) Glucose"rarr. "ethyl alcohol"),("(C) Ptyalin","(iii) Starch" rarr." Maltose"),("(D) Zymase ","(iv) Starch "rarr." Sugar"):}`

Options

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

Answer

To solve the problem of matching Column I with Column II, we will analyze each enzyme or substance in Column I and determine its corresponding product or function in Column II.

### Step-by-Step Solution:

1. **Identify the function of Diastase (A)**:
- Diastase is an enzyme that breaks down starch into maltose.
- Therefore, we match Diastase (A) with (iii) Starch → Maltose.

2. **Identify the function of Pepsin (B)**:
- Pepsin is a digestive enzyme that breaks down proteins into smaller peptides (peptones).
- Thus, we match Pepsin (B) with (i) Proteins → Peptones.

3. **Identify the function of Ptyalin (C)**:
- Ptyalin is another name for salivary amylase, which also acts on starch to convert it into maltose.
- Hence, we match Ptyalin (C) with (iii) Starch → Maltose.

4. **Identify the function of Zymase (D)**:
- Zymase is a complex of enzymes that converts glucose into ethyl alcohol (ethanol) during fermentation.
- Therefore, we match Zymase (D) with (ii) Glucose → Ethyl alcohol.

### Summary of Matches:
- (A) Diastase → (iii) Starch → Maltose
- (B) Pepsin → (i) Proteins → Peptones
- (C) Ptyalin → (iii) Starch → Maltose
- (D) Zymase → (ii) Glucose → Ethyl alcohol

### Final Matching:
- A - (iii)
- B - (i)
- C - (iii)
- D - (ii)

### Correct Options:
From the analysis, we can conclude that the correct matches are:
- A → (iii)
- B → (i)
- C → (iii)
- D → (ii)
