The passage that shows sequential organization is "first, fill the ice cube trays with water. then place them gently in the freezer door and wait two hours."
Explanation:
The sequential organization is a writing structure that follows a chronological pattern, mainly used to give instructions, step by step or to tell stories in the order the events happened, then C is the only option that follows that patter by organizing the actions in 3 steps, First, fill. Then, place. and Finally, wait. the other options do not have that organization.
The passage that shows a sequential organization is C.
Because it goes from one action to another and another, showing that you must follow a sequence or organization. In phrases like that one, it is normal to see words like first/firstly/ First of all, second/secondly, then, after that, as soon as, Finally, next, etc. in order to let you know wich is the order of the action.
