The pattern of reasoning exhibited by the argument above is most similar to that exhibited by which of the following?
A)Whenever Charlie washes his car, he takes it to either Superwash or Maxwash. Maxwash was closed this morning, so Charlie must have taken his car to Superwash.
B)Wanda is grumpy whenever she can't eat breakfast, and she can't eat breakfast whenever she has to arrive at work before 8 AM. Therefore, Wanda is only grumpy on days she has to arrive at work before 8 AM.
C)There are no bananas in Rosa's kitchen. Since Rosa always eats at least one banana per day, and she always keeps her bananas on the counter, someone else must have eaten all of Rosa's bananas.
D)Kurt's boots are covered in mud, and they only get muddy when he goes to his cousin's farm. Kurt's boots were muddy this morning, so he must have visited the farm.
E)Alyssa went to either the grocery store or the deli today, but not both. Since she came home with deli meat, it is clear she went to the deli and not the grocery store.
