Answer:
Synaptic cleft
Explanation:
Synapse is the region where the impulse is conducted between two neurons. This occurs because two neurons are in maximum possible proximity to each other at the synapse.
However, there is no physical contact between two neurons even at the synapse. And a small space is present between two neurons at synapse. This gap is called the synaptic cleft. The neurotransmitters are released in this cleft.

<em>The correct option is C) chlorine</em>
Explanation:
Sea water contains salts in abundance. It can be described as the water which makes up the oceans and the seas. It is known to contain approximately 96.5% water and 2,5 percent of salts. Sodium and chloride ions are the most abundant salt ions to be found in the sea. The concentration of chloride ions is 0.546 mol/kg and the concentration of sodium ions is 0.469 mol/kg. Hence, chloride ions are slightly abundant than sodium ions.
