Solution Explained:

To solve this problem, we apply the core principles of Photoelectric Effects and deBroglie Equation. Understanding the underlying formula is key to arriving at the correct answer below:

According to the de-Broglie relation, $\lambda = \frac{h}{p}$. If the wavelength $\lambda$ is the same, then the momentum $p$ must also be the same.
