Select the wrong pair:

Options

A. Haldane: Hot dilute soup
B. Oparin: Coacervate
C. Fox: Microspheres
D. Spallanzani: Abiogenesis

Answer

To solve the question "Select the wrong pair," we need to analyze each of the pairs provided in the options.

### Step-by-Step Solution:

1. **Identify the First Pair: Haldane and Hot Dilute Soup**
- J.B.S. Haldane proposed the concept of a "hot dilute soup," which refers to the prebiotic conditions on early Earth where life may have originated. This pair is correctly matched.

2. **Identify the Second Pair: Operon and Coacervates**
- The term "coacervates" was indeed associated with Alexander Oparin, who proposed that these structures could have been precursors to living cells. This pair is also correctly matched.

3. **Identify the Third Pair: Fox and Microspheres**
- Sidney Fox demonstrated the formation of microspheres from proteinoids. This pair is correctly matched as well.

4. **Identify the Fourth Pair: Spallanzani and Abiogenesis**
- Lazzaro Spallanzani conducted experiments that disproved spontaneous generation (abiogenesis) by showing that boiled broths did not develop microorganisms unless exposed to air. His work supported the concept of biogenesis, which states that life arises from existing life. Therefore, this pair is incorrectly matched as it suggests he supported abiogenesis.

### Conclusion:
The wrong pair is **Spallanzani and Abiogenesis** because Spallanzani's experiments were aimed at disproving abiogenesis and supporting biogenesis.

### Final Answer:
The wrong pair is **Spallanzani and Abiogenesis**.
