Distilled water is devoid of any solutes. It contains no additional gases, minerals, or contaminants. Would it be right to give a person an IV (intravenous) therapy of distilled water?

Yes. Distilled water is pure and will cause no harm.
Yes. The IV will be isotonic to the cell cytoplasm, so it will have no adverse effect on the cells.
No. The IV will be hypertonic compared to the cell cytoplasm causing the cells to shrivel.
No. The IV will be hypotonic compared to the cell cytoplasm causing the cells to explode.
