Match the following
`{:("1) Crop ","a) Sieve & grinding mill"),("2) Gizzard ","b) 6-8 finger like structures"),("3) Hepatic caecae ","c) Thin walled"),("4) Peritriophic ","d) Network of chitin"),(" membrane"," fibrils in glrcoprotein "):}`

Options

A. 1-c, 2-a, 3-b, 4-d
B. 1-a, 2-b, 3-c, 4-d
C. 1-b, 2-a, 3-c, 4-d
D. 1-d, 2-b, 3-6, 4-a

Answer

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

1. **Crop**: The crop is a structure in the digestive system of certain animals, including cockroaches. It functions as a thin-walled storage organ for food. Thus, it matches with:
- **C) Thin walled**.

2. **Gizzard**: The gizzard is known for its role in grinding food, acting like a sieve or grinding mill. Therefore, it matches with:
- **A) Sieve & grinding mill**.

3. **Hepatic caecae**: These structures are present at the junction of the midgut and hindgut. They are typically 6 to 8 in number and have finger-like projections. Hence, they match with:
- **B) 6-8 finger like structures**.

4. **Peritrophic membrane**: This membrane is a protective layer in the digestive tract, composed of a network of chitin and glycoproteins. Thus, it matches with:
- **D) Network of chitin fibrils in glycoprotein**.

Now, we can summarize the matches:
- 1) Crop → C) Thin walled
- 2) Gizzard → A) Sieve & grinding mill
- 3) Hepatic caecae → B) 6-8 finger like structures
- 4) Peritrophic membrane → D) Network of chitin fibrils in glycoprotein

The correct sequence of matches is:
1C, 2A, 3B, 4D.

### Final Answer:
1) Crop → C) Thin walled
2) Gizzard → A) Sieve & grinding mill
3) Hepatic caecae → B) 6-8 finger like structures
4) Peritrophic membrane → D) Network of chitin fibrils in glycoprotein
