Answer:
The lactose present prevents the production of lactase
Explanation:
This question is describing a set of genes in bacteria called LAC OPERON. Lac operon controls the production of lactase, which is the enzyme that digests lactose. However, this gene can be regulated at the transcription level i.e caused to be transcribed or not depending on certain factors.
According to the question, lac operon, which regulates the production of enzymes will be transcribed and subsequently translated i.e. turned on when there is a substrate (lactose) that the produced enzyme will work on. However, when there is no need of the lactase enzyme or there is absence of lactose (substrate), the lac operon gene is turned off.
Note that, the statement that "The presence of lactose prevents the production of lactase" is not correct.

The answer would be d) phenotype. The phenotype is the physical characteristic while the genotype is the combination of alleles from the parent--basically the part that you can't really see. The color of a flower is prominent, so that would be its phenotype. An organism's phenotype can also include certain behavioral characteristics as well, not just the way it looks! Hope this helped :)
