C. ions across a cell membrane
because ion channels move ions, not molecules or proteins. i believe they transport sodium (Na+) and potassium (K+) ions

yes, most all neurons will have both voltage-gated and ligand-gated channels the answer to your question is yes there is nothing about the properties of action potential necessitating direction in fact, they do go in both directions e.g. axo-axonic synapses i.e. synapse in which the axon of one neuron comes in contact with the axon of another neuron when first taught concepts of biopsych and/or neuroscience we're taught simply i.e. the most basic level otherwise it's too confusing to learn, at least in pedagogical theory i am human too
