The reason that D is the correct answer is because it directly supports and gives some more information about the topic sentence. For example, Option A only gives a statistic for an entirely different topic - it doesn't have anything to do with gathering the recipe materials. Option B talks about making an omelet, however, the topic sentence does not talk about making omelets. Lastly, C is not the right answer because it says the word "Finally" which means that it is a concluding sentence and the concluding sentence does not develop a topic sentence. Therefore, D is the correct option.
