Given below are two statements:
Statement $I$ : The decrease in first ionization enthalpy from $B$ to $Al$ is much larger than that from $Al$ to $Ga$.
Statement $II$ : The d orbitals in Ga are completely filled.
In the light of the above statements, choose the most appropriate answer from the options given below
