Match the following and choose the correct combination from the options given
`{:("Column I", "Column II"), ("Robert Hooke", 1."Mutation theroy"),("Charles Darwin",2."Swan-necked flask experiment"),("Hugo de vries ", 3."Origin of species"),("Louis pasteus",4."Mcrographia"):}`

Options

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

Answer

To solve the matching question, we need to correctly pair each scientist from Column I with their respective discovery or contribution from Column II. Let's go through each scientist one by one.

### Step-by-Step Solution:

1. **Identify Robert Hooke's Contribution:**
- Robert Hooke is known for his discovery of cells and he wrote about this in his book titled "Micrographia."
- **Match:** Robert Hooke → 4. "Micrographia"

2. **Identify Charles Darwin's Contribution:**
- Charles Darwin is famous for his work on the theory of evolution, particularly his book "On the Origin of Species," which discusses natural selection.
- **Match:** Charles Darwin → 3. "Origin of Species"

3. **Identify Hugo de Vries' Contribution:**
- Hugo de Vries is known for proposing the mutation theory, which states that mutations can lead to variations in species.
- **Match:** Hugo de Vries → 1. "Mutation Theory"

4. **Identify Louis Pasteur's Contribution:**
- Louis Pasteur is well-known for his experiments with the Swan-necked flask, which demonstrated that microorganisms come from other microorganisms, not spontaneously from non-living matter.
- **Match:** Louis Pasteur → 2. "Swan-necked flask experiment"

### Final Matching:
- Robert Hooke → 4. "Micrographia"
- Charles Darwin → 3. "Origin of Species"
- Hugo de Vries → 1. "Mutation Theory"
- Louis Pasteur → 2. "Swan-necked flask experiment"

### Correct Combination:
Thus, the correct combination is:
- 4 (Robert Hooke) - 3 (Charles Darwin) - 1 (Hugo de Vries) - 2 (Louis Pasteur)

### Answer:
The answer to the question is option 4: 4, 3, 1, 2.
