Answer:
A. Lynching increased with the start of the Jim Crow era and then declined slowly.
Step-by-step explanation:
you can see in the graph the slow decline as each bar gets smaller and smaller.
based on the graph, other choices seem to be incorrect.
- lynching did NOT increase in frequency with each passing year
- lynching was definitely a serious problem in the late 1800s but did NOT disappear completely afterward
- lynching was NOT the same level in the late 1800s and early 1900s
also the jim crow era lasted from 1877-1950s (or 1965 depending on how one sees it) lynching increased then because the jim crow laws enforced racial segregation severely.
