The sentence that seems to match the language and culture of Cervantes's time most closely is A. He dismounted briskly from his horse, ready to engage in battle.
Cervantes wrote during the era of Baroque, which means that every writer's style was embellished and fancy and had a lot of sophisticated words. So the option that best conveys this tone and style is A. The other sentences are either too plain or too informal.
