Answer #1

Answer should be genes B and D

Reason-

As we know that the function of the insulator is to maintain a boundary between two genes and protecting a gene from regulatory effects of another gene.

Considering case one insulator present between enhancer and promoter so no effect of enhancer

Case two enhancer close to promoter of gene B so it will effect it. Insulator present before C so no effect

Enhancer close to gene D and no insulator in between.
