Sometimes the concentration of glucose inside of a cell is higher than the concentration outside of that cell, yet glucose continues to enter the cell. this is an example of passive transport active transport photosynthesis osmosis

Active transport is the right answer

Explanation:

because in active transport the  molecules move against the concentration gradient for example if the concentration of glucose is high inside the cells as compared to outside but still cells need more glucose to fulfill its metabolic requirement , so in this case cells will use energy in form of ATP to draw glucose inside the cells against the concentration gradient (means from lower to higher concentration ). This is called as active transport.
