Negative inducible.
Explanation:

Negative inducible operon includes the binding of regulatory protein with the DNA and inhibits transcription. The regulatory protein binds with the operator that prevents RNA polymerase transcription. The mutation in the negative inducible operon prevents the binding of repressor to the small molecule.
Thus, the correct answer is option (a).

Answer:
The introduction of new species in the new area make the specie invasive if there is no predator is present in that ecosystem because the predator helps in the controlling of the population of that invasive species. The big example of invasive species is rabbit in the Australia where rabbit become invasive when there is no predator is present in that region so they increase in population and destroy all vegetation of that region. So if there is no predator of a newly introduced species, it become invasive in future.
