Isn't there a negative correlation between D and F .
What is the OA? Are the displayed options the OA?

My reasoning:

We know C+ D = 100.
From the graph we can infer C and hence D

C D F
20% 80% 40%
50 50 50
65 35 50
75 25 65
85 15 75

Since the sum of C and D is a constant, there will be a negative correlation between the two. When C increases, D will decrease to keep the sum constant.

I think the answer for the first question is correct.

Note what the question says "If the SAME previews were shown to other test audience..."

C is the percent of comedy in the previews. Since the same previews are shown, the percent of comedy in them will be the same. Hence C will not vary.

The other two parameters, F and L, depend on the audience. If you change the audience, it is likely that they will change.
