The best type of organization for explaining step by step, how to get to your house from school is chronological. The correct answer is option D. Arranging the steps in a chronological order means putting it one after another based on the time it happened. A particular timeline or sequence of events is being observed.
The answer could actually be "climb" or "was climbing," but traditionally should be "climb." Hope this helps :)
