Remark : - Dont confuse respiration and breathing. They are different processes. Breathing simply means inhalation of oxygen and exhalation of carbon dioxide ; while respiration means involves breakdown of food and it is a deeper process.
The answer is b, numerous meaning more in amount
Answer:

Synapse
It carries information through electrical impulses to the cell body.
It is the gap between neurons.
It ensures that information travels in one direction only.
Explanation:
A synapse is the gap or the junction where two or more neurons or nerve cells meet together.
Also called the synaptic cleft, the synaptic gap receives the electrical signals and passes them through one nerve cell to another
The axon nerve endings release neurotransmitters which ensure that the path of transmission of impulses is only unidirectional – only from presynaptic to postsynaptic path.
The synaptic gap between a nerve cell and an effector muscle cell is referred as the neuromuscular junction.
