Macrophages are cells that play a role in the response of the immune system of mice and other mammals to invasive organisms such as bacteria. Unlike other mice, mice that are genetically incapable of making these particular cells do not show elevated levels of nitrates when infected with bacteria.
The statements above, if true, provide the most support for which of the following conclusions?
  • a)
    Mice that are unable either to make macrophages or to make them in sufficient numbers will protect themselves from bacterial infections in some other way.
  • b)
    Mice that show elevated levels of nitrates can easily fight off most types of bacterial infections.
  • c)
    In mice, macrophages play a role in the production of nitrates or inhibit a process by which nitrates are broken down or otherwise eliminated.
  • d)
    When a healthy mouse becomes infected with an invasive organism, the number of macrophages in the mouse’s body decreases.
  • e)
    Injections of nitrates into mice that lack macrophages will not enhance the ability of these animals’ immune systems to fight off infection.
Correct answer is option 'C'. Can you explain this answer?

The statements provided in the question are:
  • Macrophages are cells that play a role in the immune system's response to invasive organisms like bacteria.
  • Mice genetically incapable of making macrophages do not show elevated levels of nitrates when infected with bacteria.
Now, let's evaluate each answer choice:
(A) Mice that are unable either to make macrophages or to make them in sufficient numbers will protect themselves from bacterial infections in some other way.
There is no information in the statements that suggests alternative protection mechanisms for mice without macrophages. Therefore, this conclusion cannot be supported.
(B) Mice that show elevated levels of nitrates can easily fight off most types of bacterial infections.
The statements only provide information about mice lacking macrophages not showing elevated nitrate levels. The conclusion that elevated nitrate levels indicate the ability to fight off bacterial infections is not supported.
(C) In mice, macrophages play a role in the production of nitrates or inhibit a process by which nitrates are broken down or otherwise eliminated.
This conclusion can be supported by the given information. If mice genetically incapable of making macrophages do not show elevated levels of nitrates when infected with bacteria, it suggests that macrophages play a role in the production or regulation of nitrates in mice.
(D) When a healthy mouse becomes infected with an invasive organism, the number of macrophages in the mouse’s body decreases.
The statements do not provide any information about changes in macrophage numbers during infections. Therefore, this conclusion cannot be supported.
(E) Injections of nitrates into mice that lack macrophages will not enhance the ability of these animals’ immune systems to fight off infection.
The statements do not provide information about the effect of injecting nitrates into mice lacking macrophages. This conclusion cannot be supported based on the given information.
Based on the provided statements, the conclusion that is best supported is (C) – In mice, macrophages play a role in the production of nitrates or inhibit a process by which nitrates are broken down or otherwise eliminated.
