To help rehydrate a severely dehydrated patient suffering from cellular dehydration, a solution that is close to the body's natural electrolyte balance is typically used.
The option that is suitable for intravenous infusion in such cases is:
(d) 0.9% NaCl (normal saline)
0.9% NaCl is an isotonic solution that closely matches the electrolyte composition of human body fluids and is often used to rehydrate patients with cellular dehydration. It helps restore electrolyte balance and rehydrate cells effectively.
