Pauling's electronegativity values for elements are useful in predicting:

Given below are two statements :
Statement $I$ : The electronegativity of group $14$ elements from $Si$ to $Pb$ gradually decreases.
Statement $II$ : Group $14$ contains non-metallic,metallic,as well as metalloid elements.
In the light of the above statements,choose the most appropriate from the options given below :
