If the Na+ voltage-gated channels in a muscle cell open, the Na (sodium) ions rush inside the muscle cell and makes the cell more positive as Na ions carry positive charge on it. Due to the entry of positively charged ions inside the cell, the cell becomes less negative and more positive. This is called depolarization of cell.

Explanation:
More fluid bilayers will be formed when the saturation of the fatty acids chains on a phospholipid is decreased.
Fatty acids are present in animals, plants and other microorganisms. They are composed of the carbon chain with carboxyl group at the end of the chain. The fatty acids are the vital components of the lipids, which are the essential fat soluble components. When the saturation level of these acids is decreased, it leads to the formation of more lipid bilayers.
Hence, the correct answer is 'more fluid bilayers'.
