F and H can only testify together on Tuesday.
They can’t testify Monday because H can’t testify Monday (rule 4)
They also can’t go Wednesday. Then there would be three people on Wednesday, because Iturbe always testifies Wednesday.
That leaves only G and J to testify on Monday and Tuesday. That’s not enough, since one person must testify Monday (rule 5) and two people testify Tuesday (rule 3).
So if they testify together, F and H testify on Tuesday:
That’s really all we know. At this point, rather than think about all the possibilities, it’s better to just look at the answers and see if you’ve already solved the question.
D is CORRECT. H has to testify Tuesday. The other answers either can’t be true, or could be true but don’t have to be true.

Your website has been a tremendous help! But I think here you meant H has to testify on Tuesday. I triple checked my answer because I thought I was taking crazy pills for a minute, but answer D states Hong is scheduled to testify on Tuesday. :)
