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 $\displaystyle \geqslant \sqrt{\frac{h}{\pi}} \times \frac{1}{2 \mathrm{~m}}$. In the light of the above statements, choose the correct answer from the options given below :
