Benthos are "organisms inhabiting the seafloor" according to one source, so I would say the answer is C.
It would form a negative ion... it lacks 1 e in its valence shell., it is easier for F to accept an e than to shed all existing 7.
e= electron
<h2>

</h2><h2>
A. It has a very low pH.
</h2><h2>
B. It's dissociation is a reversible reaction.
</h2><h2>
C. It has a high H+ concentration.

D. It will release all of its OH- ions.</h2>
Explanation:
<h3>
NH3 is a weak alkali that does not dissociate fully into its solution: It's dissociation is a reversible reaction.

Reactions are also :
Reversible reaction
A reaction in which products can combine back to give reactants under same given condition .
Example : N₂+H₂-------NH₃
Irreversible reaction
A reaction in which the products cant combine back to give reactants under same set of conditions .
Example : Burning of paper
They would be neutral if their electonegativity difference was 0
