B is the best answer. The skydiver's velocity is decreased (his acceleration is slowed) by giving some of his kinetic energy to the surrounding air, causing it to heat up. On a molecular level, his kinetic energy is being lost to increase the kinetic energy of the air molecules. Faster molecules in a gas means a higher temperature of the gas, or heat energy.
