Read the assertion and reson carefully to mark the correct option out of the options given below: Assertion : Transmission of the nerve impulse across a synapse is accomplished by neurotransmitters. Reason : Transmission across a synapse usually requires neurotransmitters because there is small space i.e. synaptic cleft, that seperates one neuron from another.

A : Transmission of the nerve impulse across a synapse is accomplished by neurotransmitters . R : Transmission across a synapse usually requires neuro transmitters because there is space , i.e., synaptic cleft, that separates one neuron from another .
