GPT-4o mini · Answer

The correct response is: **The average speed of the particles increased.** As the blacksmith strikes the metal, the kinetic energy of the hammer transfers to the metal, causing the particles within the metal to move faster. This increase in the average speed of the particles leads to a rise in temperature and makes the metal more malleable.
