Solution

The correct option is B The neurotransmitter released from the pre-synaptic membrane binds to receptors on post-synaptic membrane
A. The impulse can flow directly from one neuron to other across the synapse.
B. Transmission of an impulse across synapse is very similar to impulse conduction along a single axon.
C. Impulse transmission across synapse is faster.
D. The neurotransmitter released from the pre-synaptic membrane binds to receptors on post-synaptic membrane is property of chemical synapse.
So, the correct answer is 'The neurotransmitter released from the pre-synaptic membrane binds to receptors on post-synaptic membrane
Solution'.
