C. `lamda=h//p`
D. `Deltax xx Deltap~~h//6pi`

Explanation

To solve the question regarding the Uncertainty Principle, we will break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Uncertainty Principle**:
- The Uncertainty Principle is a fundamental concept in quantum mechanics introduced by Werner Heisenberg. It states that it is impossible to simultaneously know both the exact position and exact momentum (which includes velocity) of a particle.

2. **Key Components of the Principle**:
- The principle can be mathematically expressed as:
\[ \Delta x \cdot \Delta p \geq \frac{h}{4\pi} \]
where:
- \(\Delta x\) = uncertainty in position
- \(\Delta p\) = uncertainty in momentum
- \(h\) = Planck's constant

3. **Understanding the Terms**:
- Momentum (\(p\)) is defined as the product of mass (\(m\)) and velocity (\(v\)):
\[ p = mv \]
- Therefore, the uncertainty in momentum can be expressed as:
\[ \Delta p = m \cdot \Delta v \]
where \(\Delta v\) is the uncertainty in velocity.

4. **Interpreting the Principle**:
- The principle implies that if we try to measure the position of a particle very accurately (small \(\Delta x\)), the uncertainty in its momentum (\(\Delta p\)) will increase, and vice versa. This reflects the inherent limitations in our ability to measure quantum systems.

5. **Identifying the Correct Equation**:
- From the options provided in the question, we need to identify the equation that corresponds to the Uncertainty Principle. The correct option will be the one that matches the form:
\[ \Delta x \cdot \Delta p \geq \frac{h}{4\pi} \]

### Final Answer:
The Uncertainty Principle was proposed by Heisenberg and can be expressed mathematically as:
\[ \Delta x \cdot \Delta p \geq \frac{h}{4\pi} \]
