Why B is Incorrect compare to A
So I am a little bit confused why A not B
B)G>K>F(Just one place left) so if we have to chose F>Q so Just one variable
And the rule said that if you select G>R, so It will be correct
We have just one spot left and it will be R
What am I missing

If the chairperson is a homeowner, it means exactly two representatives are selected from homeowners - P Q R S and 3 representatives from tenants - F G J K.
Let's compare (A) and (B)
(A) If G is selected, Q is also selected.
We know that if G is selected, K must also be selected. We cannot select J & M because both of them must be selected and we have only one tenant spot left, thus F must be selected. G K F are all the tenants that must be selected.
The rules then tell us that if F is selected, Q must also be selected. Thus, at least one of the homeowners must be Q per answer choice A.
(B) If G is selected, R is also selected
We can use the same inferences to establish that:
G K F must be selected from the tenants and Q must be selected from homeowners
The other homeowner could be any of P/ R/S, since either of them could be selected, we cannot say that R must always be selected in this scenario. I think you might have misconstrued the answer choice saying if G -> R as a rule, while it is a must be true inference, not a rule. Can we conclude that every time we pick G and the chairperson is a homeowner, R will also be picked? No, because it is also possible to pick R S or P along with Q, hence (B) is incorrect.
Let me know if you have any further questions.

Oh ok now I got it "I think you might have misconstrued the answer choice saying if G -> R as a rule, while it is a must be true inference, not a rule"
