Answer: Option (C) is the correct answer.

Step-by-step explanation:

A hydroxide ion is an ion that has -1 charge and contains an oxygen and hydrogen atom together.

So, basically a hydroxide ion is
OH^(-) ion.

Where as a hydrogen ion is defined as the ion in which a hydrogen atom holds a positive charge, that is,
H^(+) .

A proton is a sub-particle present inside the nucleus of an atom and it holds a positive charge. Symbol of proton is
^(1)_(1)H .

Thus, we can conclude that the statement they have a negative charge, is true of hydroxide ions.
