A cause and effect organizational structure is the most likely to use the transitional words "If/then" and "consequently."
Look at this example:
If I get my homework done, then I can go to sleep.
The cause in this statement is "getting my homework done." The effect from getting my "getting my homework done" is "I can go to sleep."
The same is with "consequently." Using the same example with different transitional words:
I got my homework done; consequently, I can go to sleep.
Again, the cause is "getting my homework done." The effect is "I can go to sleep."
Therefore, the terms "If/Then" and "consequently" show that the organisational structure of the writing using those terms is cause and effect.
The answer is C.
