Option D is the one most accurately describing Lac Operon.
The lac operon is known as an inducible system. Since Lac operon is an inducible system, it will only activate in the presence of a key molecule . The key molecule, lactose, induces the Lac operon to be activated.
Once lactose binds to the repressor, it causes it to be removed. RNA polymerase is then able to access the genes in the Lac operon and transcribe them in RNA and eventually proteins.

Answer:
The correct answer is B. Myopia is also known as nearsightedness.
Explanation:
Myopia is a refractive defect of the eye in which parallel light rays converge at a focal point located in front of the retina, instead of converging on the same retina; it is the inverse defect to farsightedness, in which the light rays reach the retina before converging.
A person with myopia has difficulty focusing well on distant objects, which causes visual acuity deficits and can also lead to headaches, strabismus, visual discomfort and eye irritation.
