Help on biology question?

3,Imagine you had these two strains of drosophila:
AA= contains the gene for Gal 4 and a UAS upstream of alcohol dehydrogenase

BB= has a UAS upstream of Beta- Galactosidase

What would you expect to be able to detect in the flies from the following crosses:

AA X AA
Options:
A.Nothing
B.Alcohol dehydrogenase
C.Alcohol dehydrogenase and beta-galactosidase
D.Beta-galactosidase

I think this is option B

BB x BB
Options:
A.Nothing
B.Alcohol dehydrogenase
C.Alcohol dehydrogenase and beta-galactosidase
D.Beta-galactosidase

I think this is option D

AA X BB
Options:
A.Nothing
B.Alcohol dehydrogenase
C.Alcohol dehydrogenase and beta-galactosidase
D.Beta-galactosidase

I think this is option C
