The correct answer is C. Active transport.

Here's why:

A. Facilitated diffusion is a process of passive transport facilitated by integral proteins, but it doesn't require energy and moves substances from a higher to a lower concentration.

B. Diffusion is a passive process where molecules move from an area of higher concentration to an area of lower concentration. It doesn't require energy or specific protein carriers.

C. Active transport is the process that describes the movement of substances from a lower to a higher concentration across a semi-permeable membrane. It requires a specific protein carrier and uses energy, which fits the description in the question.

D. Osmosis is the diffusion of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. It doesn't require energy or specific protein carriers.

E. Endocytosis is a process where cells absorb molecules by engulfing them. It does require energy, but it doesn't involve the movement of substances across a semi-permeable membrane from a lower to a higher concentration.
