Answer:
D) Beta galactosidase will not be produced.
Explanation:
Promoter is necessary to start the transcription of the structural gene. The position of promoter is important because the gene which is downstream to promoter will be transcribed and the gene upstream to the promoter will not be transcribed.
Lac operon has three structural gene lacZ, lacY, and lacA. Lac Z codes for β galactosidase, lac Z codes for permease and Lac A codes for transacetylase. So if promoter for the lac operon moves between the beta-galactosidase (lacz) gene and the permease (lacy) gene, then the beta-galactosidase gene will not be produced because it is places upstreamed to the promoter.
The correct answer is Mutualism. Mutualism is when each organism benefits from their relationship.

a gene present on the Y chromosome that triggers male development
