The question stem gives us this:

r: J, M
s: _ _
t: _ _

When we check the rules, rule 1 tells us that G goes to "s", only if H goes to "r".

Since we see that H is not in the recliner group, that means that G can't go to the sofa group. Since G has to go somewhere, it'll have to be in the table group.

r: J, M
s: _ _
t: G _

At that point, we already have the answer (D).

I normally wouldn't have picked my head up quite yet, though. Looking at our scenario, I'd ask "Who's Left?" and think, "we've already had J, M and G, so we still need an H somewhere."

H could go in sofa or table.

G and J can't go together, so we know the other member of table is M or H.

r: J, M
s: _ _
t: G M/H

We know that G can't be in sofa, so it will be two out of J, M, H.

r: J, M
s: (J, M, H) pick 2
t: G M/H

Here, it's even clearer that the only idea that's set in stone (besides the info the question stem gave us) is that G is doing the table.
