Jacobson can’t swim lap 2. If J is in 2, then O is in 1 (because O has to be directly before J). That leaves no room for M to come before O.
Answer B is CORRECT.
It might seem like D is also right. Two problems. First, if J is in 6, then O could be in 5. Then O would come directly after J. Second, D and A are really the same answer choice: If J is in lap 6 then J is also in lap 1. Two answer choices can’t be right.
