Constitutive expression describes a gene that is transcribed and translated at a constant level, regardless of environmental signals. That fits the description of a gene that is always active, with steady production of its mRNA and protein. Inducible expression requires a specific signal or inducer to turn transcription on, so it is not always on. Repressible expression is typically on but can be shut off by a regulator under certain conditions, so it isn’t continually active. Latent implies the gene is dormant and not expressed until activated later. Therefore, constitutively expressed best fits the scenario.
