Final Answer :
A
Explanation :
Since the membrane is more permeable to potassium ions (K+) than to sodium ions (Na+), more positive ions (K+) tend to move out of the cell than Na+ ions move in. This creates a situation where there are more positive ions outside the cell, leading to a net positive charge outside relative to the inside.
