(B) To determine the period of an element,we look at its position in the periodic table:$Mg$ (Magnesium) is in Period $3$,while $Sb$ (Antimony) is in Period $5$.$Ca$ (Calcium) is in Period $4$,and $Zn$ (Zinc) is also in Period $4$.$Na$ (Sodium) is in Period $3$,while $Ca$ (Calcium) is in Period $4$.$Ca$ (Calcium) is in Period $4$,while $Cl$ (Chlorine) is in Period $3$.Therefore,$Ca$ and $Zn$ belong to the same period,which is Period $4$.
