The circle in the center is an S orbital. I also see Px and Py orbitals. B and C are the only two elements on the list that have P orbitals, so it has to be one of those. Given there are two P orbitals I think it's C.
As borek said, it may be the answer the writer of the question was looking for, but for posterity this is wrong for two reasons:
(1) There are no spatial axis designations, so we can't say what orientation the p-orbitals have.
(2) Every element has, or can have, p-orbitals. There's a bit of a philosophical question of whether an orbital exists if there are no electrons in it. Even allowing for the assumption that the answer is no, atoms can still exist in excited states, in which these orbitals may become filled anyway. Even hydrogen has a filled p-orbitals (and d-orbitals, etc.) under certain conditions. Then there's the fact that the question makes no mention of whether these are neutral or charged atoms, or whether the orbitals shown are atomic or molecular orbitals.
It's just a really bad question.
