This question is missing the options. I've found the complete question online. It is the following:

What were the people called who wanted to wait for secession?

A. Confederate Supporters

B. Cooperationists

C. Immediate Secessionist

D. Secessionist Democrats

Those who wanted to wait for secession were called:

B. Cooperationists

Explanation:

Cooperationists defended the secession of the Southern states from the rest of the country. However, they wished to delay it. Cooperationists defended the idea that it would be best if more states were to secede at once instead of one at a time. So they would rather wait and, perhaps, hold a convention in order to make that decision.
