Answer: A (positive) — the air exerts an upward force (air resistance) on the parachute, opposing the downward motion.
Note: the sign (positive/negative) depends on your coordinate choice. If you take upward as positive, the force is positive; if you take downward as positive, it would be negative. Also, if the question meant the work done by air while the parachutist moves downward, that work is negative (force opposite the displacement).
