Solution
The correct option is D fluorine
Fluorine (F) has seven electrons in its outermost shell. These electrons are bound tightly by the nucleus. Fluorine tends to gain an electron, whereas the other given elements tend to lose electrons to achieve the nearest noble gas electronic configuration. Hence, it is more difficult for fluorine to lose an electron and it requires the maximum energy to do so.
