Which statement describes the 3 d , 4 s , and 4 p orbitals of Arsenic As based on its electronic configuration and position in the periodic table?

Arsenic has atomic number 33, so its electron configuration ends in 3d¹⁰ 4s² 4p³. The 3d subshell holds 10 electrons and the 4s subshell holds 2, so both are completely filled. The 4p subshell can hold 6 electrons, but arsenic has only 3 there, so it is partially filled; this matches choice A.
