(B) The electronic configuration of lanthanoids is $[Xe] 4f^{1-14} 5d^{0-1} 6s^2$,while for actinoids it is $[Rn] 5f^{1-14} 6d^{0-1} 7s^2$. In actinoids,the energy difference between the $5f$ and $6d$ orbitals is much smaller than the energy difference between the $4f$ and $5d$ orbitals in lanthanoids. Additionally,because the $5f$ orbitals are further from the nucleus,they are less tightly held,allowing for greater participation in bonding and the exhibition of a wider range of oxidation states.

The main reason for the actinoids exhibiting a larger number of oxidation states than the lanthanoids is:
