C. Rashmi only
D. Sarita and Rashmi only

Explanation

To determine which friend made an incorrect statement about the muscles in our body, let's analyze each statement step by step.

### Step 1: Analyze Sarita's Statement
- **Sarita's Statement:** "Muscle P never take rest. They are found in the organ which does not function under our control."
- **Analysis:** Sarita is describing smooth muscles. Smooth muscles are indeed involuntary, meaning they function without our conscious control. They are found in organs like the intestines and blood vessels, and they do not rest as they continuously perform their functions.

### Step 2: Analyze Gaurav's Statement
- **Gaurav's Statement:** "Muscles function under our control and are involved in the movement of the body."
- **Analysis:** Gaurav is referring to skeletal muscles. Skeletal muscles are voluntary muscles, meaning we can control them consciously. They are responsible for movements such as walking, lifting, and other physical activities. His statement is correct.

### Step 3: Analyze Rashmi's Statement
- **Rashmi's Statement:** "Muscles R work on their own but can get fatigued. They are found in our heart."
- **Analysis:** Rashmi is talking about cardiac muscles. Cardiac muscles do work involuntarily, meaning they function without conscious control. However, the claim that they can get fatigued is incorrect. Cardiac muscles are designed to work continuously without tiring, which is essential for the heart's function.

### Conclusion
- After analyzing all three statements, we find that:
- Sarita's statement is correct about smooth muscles.
- Gaurav's statement is correct about skeletal muscles.
- Rashmi's statement is incorrect because cardiac muscles do not get fatigued.

Thus, the friend who made the incorrect statement is **Rashmi**.

### Final Answer
**Rashmi made the incorrect statement.**
