The sentence that correctly shows how the apostrophe is used to form a contraction is:
Fred noted it's poor time to plant spring flowers until after the last frost.
In this sentence, "it's" is the contraction for "it is."
However, it’s worth noting that the sentence is grammatically incorrect because "it's" should be used as "it is," and the correct phrase should be "it’s a poor time."
Let’s break down the other sentences:
- "The storm's arrival on Friday will bring much-needed rain." (Here, “storm's” shows possession, not contraction.)
- "The missing notebook contained all of teacher's information for the field." (Here, “teacher's” also shows possession, not contraction.)
- "Molly's options for course to study next semester are unlimited." (Again, “Molly's” shows possession.)
Therefore, the correct answer for contraction usage is indeed Fred's sentence, though grammatically it needs adjustment.
