This question gives us two new rules. K comes right before H and L is right before F.
This tells us that F has to go on day 3. If F was on 5 then the new rule would force L to go on 4. But L can’t go on 4.
Therefore J can’t be on day 1. If J were there, then the second rule says H would go on day 2, where L has to be.
Next, where we can put the K, H and G bloc?
We can’t put them on 4, 5 and 6. If K goes on 4 then L goes on 5.
We have to put them in 5, 6 and 7. That leaves only day 4 for J.
D is CORRECT. J goes in 4.
