Answer:
A.
Step-by-step explanation:
If General George McClellan had launched an attack promptly during the American Civil War, it's possible that many lives could have been saved, as decisive action might have prevented further casualties and hastened the resolution of the conflict. McClellan's caution and reluctance to engage in offensive operations were criticized by many at the time, and his delays in taking action often allowed the Confederate Army, commanded by General Robert E. Lee, to regroup and strengthen their positions, resulting in more protracted battles and casualties.
