Options

A. i - Brain, ii - spinal cord
B. i - spinal cord, ii - nephron
C. i - fiephron, ii - cell body
D. i - cell body, ii - brain

Answer

To complete the statement "___i___ and ____ii____ are the sites for information processing and controlling," we need to identify the correct components of the nervous system responsible for these functions.

### Step-by-Step Solution:

1. **Identify the Function**: The question asks for sites responsible for information processing and controlling in the body. We need to think about the systems in our body that handle these tasks.

2. **Recall the Nervous System**: The nervous system is primarily responsible for processing information and controlling responses in the body. It consists of different parts, including the brain and spinal cord.

3. **Determine the Key Components**:
- The **brain** is the central organ that processes information. It interprets sensory data, makes decisions, and sends commands to the body.
- The **spinal cord** acts as a pathway for signals between the brain and the rest of the body. It also has reflex actions that control certain responses without direct involvement from the brain.

4. **Fill in the Blanks**: Based on the above information, we can fill in the blanks:
- i: Brain
- ii: Spinal Cord

Thus, the completed statement is: "Brain and Spinal Cord are the sites for information processing and controlling."

### Final Answer:
**Brain and Spinal Cord**
