Recall the shapes and orientations of atomic orbitals: s orbitals are spherical, p orbitals have a dumbbell shape, and d orbitals have more complex shapes like cloverleaf or donut-shaped.
Identify the shape of the orbital in the diagram: since it is dumbbell-shaped, it corresponds to a p orbital rather than an s or d orbital.
Determine the axis along which the dumbbell is oriented: the problem states it is along the x-axis, so the orbital must be a p orbital aligned with the x-axis, which is denoted as $2p_x$.
Recall that $1s$ orbitals are spherical and do not have directional orientation, so option A is incorrect.
Recognize that $2p_z$ orbitals are oriented along the z-axis, and $3d_{z^2}$ orbitals have a different shape, so options C and D are incorrect, confirming that the orbital shown is $2p_x$.
