Solution

The correct option is B
Chemical synapse

The information always flows from a presynaptic neuron to the postsynaptic neuron in a chemical synapse. However, in electrical synapses where neurons or muscle cells are connected by gap-junctions, the information can flow bidirectionally as ions carrying the electrical charge can traverse in both directions; usually seen in cardiac muscles.
