<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
We are given an image having electrons around the nucleus of an atom.
Total number of electrons around the nucleus = 2 + 6 = 8
The electronic configuration of the element having 8 electrons is:
As, the last electron is entering p-subshell, the element belongs to p-block of the periodic table.
The rule for determining the group number for p-block element is:
Group number = Number of valence electrons + 10
The number of valence electrons = 2 + 4 = 6
Group number = 6 + 10 = 16
Hence, the correct answer is Option C.
