Ligand-gated ion channels are ; g protein-coupled receptors are a. slow/ionotropic; fast/metabotropic b. fast/ionotropic; slow/metabotropic c. slow/metabotropic; fast/ionotropic d. fast/metabotropic; slow/ionotropic

The answer is b. fast / ionotropic; slow / metabotropic. There is fast neurotransmission since the ligand – gated ion channel receptor is directly activated by the neurotransmitter.  On the other hand, G – protein coupled receptor is bound to the neurotransmitter in order to stimulate a chemical signaling cascade which has a longer pathway, thus, making it slow and metabotropic.
