Final answer:
The incorrect statement is that conscription laws in the Union and Confederacy instigated draft riots due to immigrants fearing that freedmen would take their jobs after the war. In reality, the draft riots were primarily driven by socioeconomic tensions and class divisions.
Step-by-step explanation:
The incorrect statement concerning conscription laws in the Union and Confederacy is option B. Conscription laws in the Union did lead to draft riots, but it was not because immigrants feared that freedmen would take their jobs after the war.
In reality, the draft riots were primarily driven by socioeconomic tensions and class divisions. Wealthy individuals could hire substitutes or pay a fee to avoid military service, which created resentment among the poor. This led to widespread unrest, particularly in New York City, where working-class citizens felt most aggrieved by the draft policies.
However, the fear of freedmen taking their jobs after the war was not a significant factor in the draft riots.
