The correct answer is b) 3.
Explanation: The p sublevel consists of three orbitals. These orbitals are designated as px, py, and pz, and they are oriented in specific directions within an electron cloud. Each p orbital can hold a maximum of two electrons, meaning the entire p sublevel can accommodate a total of six electrons. Understanding the arrangement and number of orbitals in each sublevel is essential in the context of quantum mechanics and atomic structure.
