Match the following columns and find correct combination:
`{:("Column I", "Column II"),("a Darwin", "p Mutation theory"),("b De Vries", "q Protobiosis"),("c Pasteur", "r Origin of species"),("d Fox" ,"s Special Creation"),(,"t Swan-Necked"),(," Flask Experiment"):}`

Options

A. d = r, b, = p, c = t, J = q
B. a = p, b = q, c = r, d = s
C. a = t, b = r, c = q, d = p
D. a = r, b = t, c = p, d = q

Answer

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

### Step-by-Step Solution:

1. **Match "Darwin" (a)**:
- Darwin is known for his work on the theory of evolution, particularly through his book titled "Origin of Species."
- Therefore, we match **a (Darwin)** with **r (Origin of species)**.

2. **Match "De Vries" (b)**:
- De Vries is associated with the mutation theory, which explains how mutations can lead to evolutionary changes.
- Thus, we match **b (De Vries)** with **p (Mutation theory)**.

3. **Match "Pasteur" (c)**:
- Pasteur is famous for his swan-necked flask experiment, which demonstrated that microorganisms do not spontaneously generate.
- Hence, we match **c (Pasteur)** with **t (Swan-Necked Flask Experiment)**.

4. **Match "Fox" (d)**:
- Fox is known for his work on protobiosis, which relates to the origins of life and the early stages of biological development.
- Therefore, we match **d (Fox)** with **q (Protobiosis)**.

### Final Combinations:
- a → r (Darwin → Origin of species)
- b → p (De Vries → Mutation theory)
- c → t (Pasteur → Swan-Necked Flask Experiment)
- d → q (Fox → Protobiosis)

### Correct Combination:
The correct matches are:
- a → r
- b → p
- c → t
- d → q
