Assertion (A): Action potential is generated due to the exit of sodium ions from the neuron through the plasma membrane. Reason (R): Movement of sodium ions through the plasma membrane takes place under the influence of a stimulus.

A list of events occurring in the transmission of nerve impulse across the synapse is given below in a random order (i)Opening of specific ion channels allows the entry of ions, a new action potential is generated in the post-synaptic neuron. (ii)Neurotransmitter binds to the receptor on post synaptic membrane. (iii)Synaptic vesicle fuses with pre-synaptic membrane, neurotransmitter release into synaptic cleft. (iv)Depolarisation of pre-synaptic membrane. (v)Arrival of action potential at axon terminal. Which of the following options represents these events in a correct order ?
