The best answer is B (semi permeable)
The cell membrane of a red blood cell is semi permeable membrane. This is a type of biological membrane that will allow certain molecules or ions to pass through while barring others.
Red blood cells have very thin membranes that allow oxygen diffuse through quickly. They are also permeable to water and osmosis across the membrane occurs very rapidly. In the body, they are bathed in isotonic plasma in which case water movement into the cell is equal to water movement out of the cell and so the cells remain intact.

<h3>Anthrax is an uncommon, but deadly, disease produced by Bacillus anthracis, a spore-forming bacterium.</h3>
<u>Explanation</u>
- Anthrax bacteria usually enter the body through a skin wound. You can have become infected if you intake tainted meat or inhale the spores.
- ID50, the number of microorganisms needed to create a demonstrable infection by 50 percent.
- The ID50 for cutaneous anthrax attributable to Bacillus anthracis is 10-50 endospores, while the ID50 for inhalation anthrax is 10,000 to 20,000 endospores.
- Ciprofloxacin is the alternative treatment for anthrax when mutated forms are identified. It is suggested for post- inhalation anthrax.
