Answer

To solve the question, we need to fill in the blanks in the three statements provided. Let's analyze each statement step by step.

### Step 1: Analyze Statement (A)
**Statement (A)**: For a long time it was also believed that life came out of decaying and rotting matter like straw, mud, etc. This was the theory of **i**.

- The theory that explains the origin of life from decaying matter is known as **spontaneous generation** or **abiogenesis**.

### Step 2: Analyze Statement (B)
**Statement (B)**: During post-industrialization period, the tree trunks became dark due to industrial smoke and soots. Under this condition the **i** did not survive due to predators, while **ii** survived.

- In this context, we are discussing the phenomenon observed in moths during the industrial revolution. The **i** refers to the **light-colored moths**, which did not survive due to being easily spotted by predators. The **ii** refers to the **dark-colored (melanic) moths**, which survived because they blended in with the darkened tree trunks.

### Step 3: Analyze Statement (C)
**Statement (C)**: Lamarck said that evolution of life forms had occurred but driven by **i** of organs.

- Lamarck proposed the theory of **use and disuse of organs**. He believed that organs that were used more frequently would become stronger and more developed, while those that were not used would diminish over generations.

### Summary of Answers
Now we can summarize the correct fillings for the blanks:
- (A) **spontaneous generation**
- (B) **i: light-colored moths; ii: dark-colored moths**
- (C) **use and disuse**

### Final Answer
The correct option that fills the blanks in the statements is:
- (A) spontaneous generation
- (B) i: light-colored moths; ii: dark-colored moths
- (C) use and disuse
