Solution

The correct option is C The atomic radii of the elements of group 16 is larger than those of the corresponding elements of group 15
The general electronic configuration of group 16 elements is ns2np4.
Electronic configuration of O=[He]2s22p4
Electronic configuration of S=[Ne]3s23p4
Electronic configuration of Se=[Ar]3d104s24p4
​​​​​​​Electronic configuration of Te=[Kr]4d105s25p4
​​​​​​​Electronic configuration of Po=[Xe]4f145d106s26p4
​​​​​​​
When we move across the periodic table, from left to right, the atomic size of the respective elements decreases due to increase in nuclear charge. Therefore, the atomic radii of the elements of group 16 is smaller than those of the corresponding elements of group 15.
