Solution

The correct option is C Uphill transport
Facilitated transport is the process of spontaneous passive transport or downhill transport of molecules. In this transport mechanism, molecules move from a region of higher concentration to a region of lower concentration along the concentration gradient. Specific membrane proteins are involved in this movement and thus this type of transportation is highly specific. Thus, the correct answer is option C.
