D

Verified step by step guidance1
Understand that a hydrogen ion (often represented as H\textsuperscript{+}) is formed when a hydrogen atom loses its single electron during dissociation.
Recall that a neutral hydrogen atom has one proton (positive charge +1) and one electron (negative charge -1), so the net charge is zero.
When the hydrogen atom loses its electron, it is left with only the proton, which carries a positive charge of +1.
Therefore, the hydrogen ion formed during the dissociation of water carries a charge of +1.
This explains why the correct answer is +1, as the hydrogen ion is essentially a proton with a single positive charge.
