Answer:
C. Virus-infected cells
Read Explanation:
Interferons are proteins that are primarily secreted by virus-infected cells in response to viral infection.
A virus-infected cell releases interferons to signal neighboring cells and the immune system that the virus is present.
Interferons play a crucial role in coordinating the body’s immune response to combat viral infections.
While interferons are mainly produced by virus-infected cells, they can also be produced by other cell types, such as lymphocytes, including natural killer (NK) cells, B cells, and T cells, in response to viral infection or immune stimulation.
Nevertheless, interferons are not secreted by all cells in the body.
The liver and spleen, as organs, do not produce interferons themselves, but their antiviral effects may affect them.
