The role of the presynaptic neuron in a synapse is to release neurotransmitters. The presynaptic neuron is the neuron that is sending the signal across the synapse. When an action potential reaches the end of the presynaptic neuron's axon, it triggers the release of neurotransmitters into the synapse. These neurotransmitters then bind to receptors on the postsynaptic neuron, causing a response in that neuron. In other words, the presynaptic neuron is responsible for transmitting signals to the postsynaptic neuron by releasing neurotransmitters into the synapse. Therefore, option 3 is the correct answer.
