Math column I with column II and select the correct option from the codes given below
`{:("Column I","Column II"),(A." Food",(i)." Brown algae"),(B." Agar",(ii)." Porphyra, Laminaria"),(C."Algin",(iii)." Gelidium, Gracilaria"),(D." Carrageenin",(iv)." Red algae"):}`

Options

A. A-ii,B-iii,C-I,D-iv
B. A-ii,B-iii,C-iv,D-i
C. A-iii,B-ii,C-iv,D-i
D. A-iii,B-ii,C-I,D-iv

Answer

To solve the matching question between Column I and Column II, we will go through each item in Column I and identify the corresponding item in Column II based on the information provided.

### Step-by-Step Solution:

1. **Identify the first item in Column I: "Food" (A)**
- The question states that many algae are used for food production. The examples given are **Porphyra** and **Laminaria**.
- Therefore, the match for "Food" is **(ii) Porphyra, Laminaria**.

2. **Identify the second item in Column I: "Agar" (B)**
- Agar is a substance used for microbial growth and is derived from certain algae. The transcript mentions that agar is obtained from **Gelidium** and **Gracilaria**.
- Thus, the match for "Agar" is **(iii) Gelidium, Gracilaria**.

3. **Identify the third item in Column I: "Algin" (C)**
- Algin is described as a hydrocolloid substance that can hold water and is obtained from **brown algae**.
- Hence, the match for "Algin" is **(i) Brown algae**.

4. **Identify the fourth item in Column I: "Carrageenin" (D)**
- Carrageenin is mentioned as being obtained from **red algae**.
- Therefore, the match for "Carrageenin" is **(iv) Red algae**.

### Summary of Matches:
- A (Food) → (ii) Porphyra, Laminaria
- B (Agar) → (iii) Gelidium, Gracilaria
- C (Algin) → (i) Brown algae
- D (Carrageenin) → (iv) Red algae

### Final Matching:
- A → ii
- B → iii
- C → i
- D → iv

### Conclusion:
The correct option is **(A-ii, B-iii, C-i, D-iv)** which corresponds to **Option 1** as per the provided codes.
