Answer:
B. Speaking is more immediate than writing.
Step-by-step explanation:
Using the process of elimination, the answers A and C do not make much sense. D states that speaking is more "lasting" than writing, which doesn't make such sense either. B is the answer because it makes the most sense. When you are speaking, you can think of things to say a lot faster than when you are writing.
Hope this helps!! Have a great day C:
