hello,
Heterotrophic. Only plants have cell walls, so that goes to phytoplankton, and whales have thousands of cells, so unicellular goes to plankton again. Mammals aren't prokaryotic, so we're left with heterotrophic.

Answer:
Negatively repressible.
Explanation:
A control which occurs through repressor is known as negative control which may be inducible or repressible.
When a small molecule named as allolactose binds this repressor it leads to allosteric repulsion which removes repressor from the operator as a result of which RNA polymerase can start transcription. Allolactose is therefore known as inducer because it induces lac operon expression.
But here, the operator is active (induced) already so there is no need to induce the operon which means that it can only be repressed so that transcription could stop. So the answer is negatively repressible operon.
