Answer: D) How much time/effort does it require?
Explanation: In the given thesis statement we can see an argument that supports the idea of the fact that moving from your family home after high school, can be difficult, and it list some of the things that must be considered when moving, like cooking, cleaning and paying bills. We can see that after each category, there is a list, and that each list follows a writing or grammatical style, the cleaning list consists in nouns that denote the things that must be cleaned, the bill-paying list consists in phrases that start with a verb in the "-ing" form, and the cooking list consists in questions, so the missing piece on the cooking list is "How much time/effort does it require?"
