Homeostasis is the process of maintaining a cell's environment. This
includes the regulation of sodium ion (Na+) concentration within the
cytoplasm. If too much Na+ is inside a cell, how can the concentration be
changed?

A) More Na+ ions will be transported in through membrane protein channels

B) Excess Na+ ions will leave the cell via osmosis

C) More Na+ ions will enter the cell through the plasma membrane

D) Excess Na+ ions will be transported out though membrane protein channels

Homeostasis is the procedure of maintaining a cell's environment: Excess Na+ ions will be exhilarated out through membrane protein channels.

What is the Homeostasis process?

Homeostasis is especially crucial for the survival of organisms. It is often seen as an opposition to differences in the external environment. Similarly, homeostasis is a self-regulating process that controls internal variables required to sustain life.

The body retains homeostasis by controlling a host of variables running from body temperature, blood glucose levels to fluid balance, potassium blood pH, sodium, and calcium ion concentrations.

Therefore, The correct option is 'D'.
