The statements that describe the controversy surrounding Arkansas's decision to secede from the Union are:
C. Some groups wanted to wait to see what action President Lincoln took.
The other statements contain inaccuracies regarding the context of Arkansas's secession:
A. A succession list wanted to immediately succeed from the union - This statement incorrectly implies a uniform desire for immediate secession, when in fact there were factions with differing opinions.
B. Confederates wanted to remain part of the union - This is inaccurate, as those who identified as Confederate were generally inclined to secede.
D. Those that wanted to abolish slavery wanted to succeed from the union - This statement is misleading; abolitionists were typically against secession and supported the Union.
In summary, option C is the most accurate representation of the controversial dynamics at play during Arkansas's secession.
