Solution

The correct option is A Statement I is true, Statement II is true and is a correct explanation of the phenomena described in I
CF4 have net dipole = 0, thus non polar.
Yes CF4 have 4CF polar bonds as F being more electronegative attracts the shared paired of electrons towards itself, hence polar and CF4 have a tetrahedral geometry.
