Vedclass · Answer

(C) The ease of losing an electron is determined by the ionization energy. Elements with low ionization energy lose electrons easily. Alkali metals $(Li, Na, K)$ have the lowest ionization energy in their respective periods because they have a single electron in their outermost shell ($ns^1$ configuration),which is easily removed to achieve a stable noble gas configuration. Therefore,the correct group is $(C)$.
