Answer: (B)

Verified step by step guidance

1. Recall that an orbital is a region in space where there is a high probability of finding an electron. Each orbital can hold a specific maximum number of electrons based on quantum mechanical principles.
2. Understand that the p subshell consists of three p orbitals (px, py, pz), but the question asks about a single p orbital, not the entire p subshell.
3. Apply the Pauli Exclusion Principle, which states that each orbital can hold a maximum of two electrons, and these electrons must have opposite spins.
4. Therefore, the maximum number of electrons that can occupy one p orbital is 2.
5. Note that while the entire p subshell can hold 6 electrons (2 per orbital × 3 orbitals), each individual p orbital can only hold 2 electrons.
