Given below are two statements about X-ray spectra of elements:
Statement (I): A plot of \( \sqrt{\nu} \) (\( \nu = \) frequency of X-rays emitted) vs atomic mass is a straight line.
Statement (II): A plot of \( \nu \) (\( \nu = \) frequency of X-rays emitted) vs atomic number is a straight line.
In the light of the above statements, choose the correct answer from the options given below:
