    A chemistry student investigates three representative main-group elements, labeled X, Y, and Z. Element X has three occupied electron shells and two valence electrons, while Element Y exhibits chemical properties similar to Element X but contains one fewer electron shell. Element Z is situated in the same period as Element Y and readily forms an anion with a single negative charge to achieve a noble gas configuration. Based on their positions in the periodic table, which statement regarding elements X, Y, and Z is correct?

    • A) Element X and Element Y have different numbers of valence electrons, resulting in distinct chemical families.
    • B) Element Y possesses a greater number of occupied electron shells than Element X.
    • C) Element Z is located to the left of Element Y within the periodic table due to having a smaller atomic number.
    • D) Element Z has more valence electrons than Element Y, while Element X has more occupied electron shells than both Element Y and Element Z.
