There are two possibilities here: either J is 1st and 6th or H is 1st and 6th. However, in the scenario with J 1st and 6th, there is no place for our HJ block from rule number 3 (i.e. exactly once Sukanya receives a message from J on the day after receiving one from H).
Therefore, the only possible scenario is H 1st and 6th, which results in the following scenario:
H J L J L H
You will notice that in this scenario, which is the only possible scenario if there are six messages and L is fifth, the fourth message is from Jerome, so (D) must be true.
Hope this helps! We will upload the video explanations for this game very shortly as well. Please let us know if you have any other questions.
