Match the following columns:
`{:(,"Column I",,"Column II"),(A,"Golden rice",i,"Eli Lily"),(B,PCR,ii,"Herbert boyer"),(C,"Insulin",iii,"Kary mullis"),(D,"Recombinant DNA",iv,"Peter Bayer"):}`

Options

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

Answer

To solve the matching question, we need to associate each item in Column I with the correct item in Column II based on their contributions to biotechnology. Here’s the step-by-step solution:

### Step 1: Identify the first item in Column I - Golden Rice
- **Golden Rice** is a genetically modified rice variety that is enriched with vitamin A. It was developed to combat vitamin A deficiency.
- **Match**: Golden Rice was engineered by **Peter Bayer**.

### Step 2: Identify the second item in Column I - PCR
- **PCR** stands for Polymerase Chain Reaction, a technique used to amplify DNA sequences. It allows for the creation of millions of copies of a specific DNA segment.
- **Match**: The inventor of PCR is **Kary Mullis**.

### Step 3: Identify the third item in Column I - Insulin
- **Insulin** is a hormone that regulates blood sugar levels. The first synthetic insulin was produced using recombinant DNA technology.
- **Match**: The company that produced the first recombinant insulin is **Eli Lilly**.

### Step 4: Identify the fourth item in Column I - Recombinant DNA
- **Recombinant DNA** technology involves combining DNA from different organisms. It was a significant breakthrough in biotechnology.
- **Match**: The pioneer of recombinant DNA technology is **Herbert Boyer**.

### Final Matches:
- A (Golden Rice) → iv (Peter Bayer)
- B (PCR) → iii (Kary Mullis)
- C (Insulin) → i (Eli Lilly)
- D (Recombinant DNA) → ii (Herbert Boyer)

### Summary of Matches:
- A → 4
- B → 3
- C → 1
- D → 2

### Final Answer:
- A4, B3, C1, D2
