(B) The lanthanoid series consists of $14$ elements starting from Cerium ($Ce$,atomic number $58$) and ending at Lutetium ($Lu$,atomic number $71$).Lanthanum ($La$,atomic number $57$) is the element preceding the lanthanoids and is often studied alongside them due to its similar properties,but it is technically a $d$-block element.Therefore,the lanthanoid series is defined as $Ce$ to $Lu$.

Which of the following elements are included in the lanthanoid series?
