Given below are two statements $:$
Statement $(I):$ It is impossible to specify simultaneously with arbitrary precision,both the linear momentum and the position of a particle.
Statement $(II) :$ If the uncertainty in the measurement of position and uncertainty in measurement of momentum are equal for an electron,then the uncertainty in the measurement of velocity is $\geq \sqrt{\frac{h}{4\pi}} \times \frac{1}{m}$ which simplifies to $\geq \frac{1}{2m} \sqrt{\frac{h}{\pi}}$. In the light of the above statements,choose the correct answer from the options given below $:$

• A
  Statement $I$ is true but Statement $II$ is false.
• B
  Both Statement $I$ and Statement $II$ are true.
• C
  Statement $I$ is false but Statement $II$ is true.
• D
  Both Statement $I$ and Statement $II$ are false.
