Answer:
The correct answer is C. In the plaque assay for bacteriophages, the plaque is a clear zone caused by a zone of lysis.
Explanation:
The plaque assay is an approach used for titering bacteriophage stocks or determining the quantity of infectious virus in a sample. Plaques are visualized if you spot the phage on a lawn of growing compatible bacteria. Each plaque indicates an initial infection with one phage followed by lysis of neighboring bacteria in the lawn. Only viruses that cause visible damage of cells can be assayed in this way. The plaque assay is used to determine viral titer as plaque-forming units per ml so that known amounts of virus can be used to infect cells during subsequent work.

The given blank can be filled with medulla.
The medulla also called the medulla oblongata is the segment of the brainstem that is factually the stem, which elongates from the brain. The medulla is positioned below the pons and above the spinal cord and is a major relay intersection for information conducted to and from the spinal cord and the brain. This section of the brain is a monitoring center for circulation and respiration.

A, B, and C. Luster is the light and how light reflects off of it, right?
So, in that case, a non metallic mineral, (think coal) wouldn’t shine much. A metallic mineral would shine, because it’s metal. And something that’s shiny obviously shines.
Go with A B and C.
