The electron configuration given in the question represents a characteristic outer shell electron configuration of p-block elements. For these elements, the highest occupied energy level is the 'n' shell, and the valence electrons occupy the p subshell. Among the options, only option D has elements with ns^2np^4 and ns^2np^6 configurations, which correspond to the given form. Therefore, the correct answer is D.
