During Cell Injury Caused by Hypoxia,sodium and Water Move into the Cell

During cell injury caused by hypoxia,sodium and water move into the cell because:

A) Potassium moves out of the cell, and potassium and sodium are inversely related.
B) The pump that transports sodium out of the cell cannot function because of a decrease in ATP levels.
C) The osmotic pressure is increased, which pulls additional sodium across the cell membrane.
D) Oxygen is not available to bind with sodium to maintain it outside of the cell.
